PRESENTATION CONTENTSMy presentation is JAXA research project status about

AMSR/AMSR-E. Imaoka-san is going to present the GCOM status the day after tomorrow.

1. CALIBRATION & VALIDATION Geometric correction accuracy of Level 1B was

improved, and the most suitable parameter was decided. Mr. Susumu Saito will present these contents.

The algorithms of a sea surface temperature and a soil moisture were improved. These standard products were updated and released in March of this year.

In this Japanese fiscal year (JFY), we plan to reevaluate the calibration status, to improve the calibration method and to evaluate an influence on standard products. According to evaluation result in this JFY, we plan to improve standard products in the next JFY. 3

2. THE STATUS OF A PROTOTYPE SYSTEM FOR PROCESSING VARIOUS MICROWAVE OBSERVATION DATA We developed a prototype system for processing

various microwave observation near-real-time data. We began to operate this system experimentally in April.

Now this system makes a sea surface temperature, an ice concentration and a soil moisture from TMI, Windsat and SSM/I.

These are browse images of the day average and the week average of the SST to be calculated from TMI and WindSat.

Because the swath width is narrow and WindSat observes an area of a high latitude, we think that we can improve the observation area by using the both data.

2. THE STATUS OF A PROTOTYPE SYSTEM FOR PROCESSING VARIOUS MICROWAVE OBSERVATION DATA

We plan to add the following ; To show the products in a Web site To add to the data of GCOM-W1/AMSR2 and so on To add to the other products

3. RECENT TOPIC - IARC-JAXA INFORMATION SYSTEM (IJIS) We show the result of the

Arctic sea ice monitor with AMSR-E in the Web sites as the Arctic research.

3. RECENT ACTIVITY - IARC-JAXA INFORMATION SYSTEM (IJIS) The Arctic sea ice is

updated every day. We can watch the sea ice

of the specified date, and the movie of the specified period.

3. RECENT ACTIVITY - IARC-JAXA INFORMATION SYSTEM (IJIS) The graph of sea ice

extent is also shown and updated every day.

The arctic sea ice was recorded the smallest extent around the end of last summer.
