NPP Re-Named Jan. 2012: Suomi National Polar-orbiting Partnership

NASA Renames Earth-Observing Mission in Honor of Satellite Pioneer (01.25.12)

NASA has renamed its newest Earth-observing satellite in honor of the late Verner E. Suomi, a meteorologist at the University of Wisconsin who is recognized widely as "the father of satellite meteorology."

"Verner Suomi's many scientific and engineering contributions were fundamental to our current ability to learn about Earth's weather and climate from space," said John Grunsfeld, associate administrator of NASA's Science Mission Directorate in Washington. "Suomi NPP not only will extend more than four decades of NASA satellite observations of our planet, it also will usher in a new era of climate change discovery and weather forecasting."Verner E.

Suomi National Polar-orbiting Partnership

The NASA NPP mission will serve as a bridge between the NASA EOS satellites (and NOAA’s POES satellites) and the NOAA Joint Polar Satellite System (JPSS). It has two major goals:

• To provide a continuation of the EOS record of key Earth observations after EOS Terra, Aqua, and Aura, and

• To provide risk reduction for JPSS instruments, algorithms, ground data processing, archive, and distribution prior to the launch of the first JPSS spacecraft.

• We cannot overstate the importance of the NPP mission for Earth System Science research, long-term environmental trend monitoring and weather prediction in– Continuing the critical long-term observations from EOS and many

missions that preceded EOS, – Establishing the performance and cross-calibration relationship between

the EOS measurements and those that will be continued by JPSS, and– Providing critical data for NOAA to use operationally to support

numerical weather predictions.

• The recently re-defined NASA-NOAA partnership has successfully brought the NPP mission to completion after many difficult years of development– The partnership has accomplished great things in the past 20 months

since the reformulation of the polar satellite program– The partnership follows a long and successful NASA-NOAA model that

has delivered POES and GOES satellites for the Nation

• NPP is needed, and is ready to go.

NOAA and NASA Data Activities for Suomi NPP

NOAA JPSS Algorithm Cal/Val Teams and Comprehensive Large Array-data Stewardship System (CLASS)

• Scientific support for operational generation of NPP/JPSS sensor data records (SDRs) and Environmental Data Records (EDRs)

• Cal/val of the Interface Data Processing Segment (IDPS) generated SDRs and EDRs and ownership of the algorithms for future upgrades, and provides long-term science maintenance (validation and improvements).

• Infrastructure: GRAVITE (mini – IDPS, local archive, subscription services to cal/val teams) and CLASS for permanent archive.

NASA Suomi NPP Project Office, Science Team, and Science Data Segment (SDS)

• Evaluation of the IDPS-generated SDRs and EDRs as to their suitability as Earth system / climate data records.

• If warranted, the Suomi NPP Science Team will develop, test, and recommend algorithm improvements.

• Infrastructure: SDS includes mini-IDPS, local archive, and Product Evaluation and Analysis Tool Elements (PEATEs).

Suomi NPP Data Coordination: Summary • Initial NASA and NOAA roles and responsibilities are fairly

clear.• NOAA: Suomi NPP data processing, production, distribution,

and archive of SDRs and EDRs; cal/val; consideration of recommended algorithm improvements (this is not anticipated to change through mission life)

• NASA: SDR & EDR evaluation; recommend algorithm improvements; scientific support of cal/val (in support of EOS time series climate-quality data continuity)

• For NASA, mid-term (L + 18 mos.) responsibility is assessment of EDRs and recommendations for improvements and decision(s) on next steps for NASA during prime mission

Suomi NPP Data Coordination: Summary

• For NASA, longer term roles and responsibilities are “tbd;” what we will do and how it will be done are to be decided once the Suomi NPP Science Teams’ evaluations, product recommendations, and follow-on interactions with JPSS/NOAA are completed.

• What you should know:• NASA Suomi NPP mission responsibilities continue (and funds are planned)

through prime mission (5 years) and can extend into an extended operations period. The work is expected to evolve over the course of the mission.

• Funding for Suomi NPP Project Science, Science Team, and data product support is reserved/available, but “tbd” in budget plans for future years.

• In our future decision making we plan to take into account the initial Suomi NPP ST evaluations and recommendations, NASA’s knowledge of best practices and approaches for data support, NASA Earth Science community priorities, and national needs.

Suomi NPP Science Team Activities

New and successor investigations to continue the evaluation of NPP/NPOESS Environmental Data Records (EDRs) – also SDRs and IPs, to demonstrate the suitability of these data sets for use as Earth system/climate data records, and to develop and evaluate improvements to EDR algorithms that could make them more suitable. Support for calibration/validation was included. New investigations to develop and demonstrate innovative and practical applications of Suomi NPP data. Three were selected: global agricultural monitoring, air quality and public health, and TOPS for ecological forecasting.

The emphasis for all types of investigations is on evaluation towards securing continuous, well-characterized, long time series measurements of sufficient quality to answer critical Earth system science, global change, and/or applied sciences questions.

Page 23: Suomi National Polar-orbiting Partnership    Science June 21, 2012  Diane E. Wickland Suomi NPP Program Scientist

NPP Science Team members will be expected to:

Participate in technical interchange meetings, NPP science team meetings, and relevant measurement team meetings and more frequent teleconference calls Review sensor and algorithm documents, algorithm code, and system descriptions as appropriate; Conduct data simulation studies as appropriate Prepare an algorithm analysis report and recommend algorithm improvement activities Participate in the planning for science operations Participate in NPP calibration and validation planning as appropriate; and Provide information to NASA on a variety of technical matters associated with NPP instruments and algorithms.

NASA Data PolicyNASA promotes the full and open sharing of all data with the research and applications communities, private industry, academia, and the general public (the term 'data' includes observation data, metadata, products, information, algorithms, including scientific source code, documentation, models, images, and research results).

Relevant information excerpted from NASA’s statement at: http://science.nasa.gov/earth-science/earth-science-data/data-information-policy/

• Full and open sharing of Earth science data obtained from NASA Earth observing satellites, sub-orbital platforms and field campaigns with all users as soon as such data become available. [NOTE: This applies to any type of product!]

• No period of exclusive access to NASA Earth science data. • NASA will enforce a principle of non-discriminatory data access so that all users will

be treated equally. • NASA will make available all NASA-generated standard products along with the

source code for algorithm software, coefficients, and ancillary data used to generate these products. [NOTE: At present, NASA has no commitment to produce any Suomi NPP standard products.]

Page 25: Suomi National Polar-orbiting Partnership    Science June 21, 2012  Diane E. Wickland Suomi NPP Program Scientist

Data-Sharing Responsibilities of Suomi NPP Science Team Members

NASA expects Suomi NPP Science Team members to comply with NASA data policies; i.e., to make the results of their team member research and their data products publicly available, and, to the extent possible within exiting team member funding, to freely share these products with the external community.• There is no period of exclusive access or restriction on sharing of Suomi NPP ST

results or data products• Data products should be made available with the clear understanding that they

are PI data products (experimental) and not NASA standard products – a marking should appear on websites and product documentation so stating.

• The level of “user support” to be provided is up to the team member, but there is no requirement to provide a high level of support – just access

• User feedback on quality and issues of such experimental products may be helpful to ST Members.

• External persons contacting Suomi ST members for access to SDRs and EDRs should be referred to CLASS

• Issues regarding data access or user interest/support should be brought to the attention of the Project Scientist (for referral to NASA HQ, JPSS, or NOAA, as appropriate)

Suomi NPP ST Meeting Goals & Objectives

Our primary goals: Discuss Suomi NPP Science Team responsibilities (SDR/EDR/IP

evaluation, cal/val support, preparatory work toward new data products) and progress to date

Identify in some detail near-term activities/actions and schedules.

We should all leave the meeting very clear on the: Process for EDR evaluation Reporting on EDR evaluation results Schedule for initial/complete evaluations Steps to follow (recommend improvements, alternative products, etc.) NASA data policy and data sharing expectations / processes

Suomi NPP ST Evaluation Research Reports

• Evaluating Sensor Data Records (SDR), Environmental Data Records (EDR), and Intermediate Products (IP)

• Emphasizing SDR and calibration evaluation• Looking at time series data as well as regional and seasonal

patterns• Comparing against airborne and surface-based observations• Cross-product evaluation (w/EOS and international sensor data)

• Identifying and prioritizing performance issues and concerns for further investigation

• Identifying needed supporting data and information (e.g., updated DEM and water mask for the land)

• Evaluating potential changes to the IDPS products• Recommending/evaluating new products• Schedule for reporting on evaluations of products:

• Preliminary reports are anticipated summer 2012 - November 2013

• Final reports are anticipated May 2013 - June 2014

Page 29: Suomi National Polar-orbiting Partnership    Science June 21, 2012  Diane E. Wickland Suomi NPP Program Scientist

Top-Level ST Findings and Recommendations

• Review of existing and new products is needed (ATBDs were useful, perhaps new focus should move to experimental products and peer reviewed publications)

• It is not just the data products that need to be evaluated and secured, it is also the data services (e.g., LANCE-like services)

• At a minimum, data record continuity requires algorithm continuity; NASA should consider re-focusing the team on designing consistent EOS / Suomi NPP Level-2 algorithms

• Once SDR evaluation is complete, NASA should begin generating test products for those current EOS products without a Suomi NPP EDR equivalent

• The ST is seeking opportunities to engage the broader research community
