S-‐NPP/ CERES FM5 INSTRUMENT STATUS
S-‐NPP/CERES FM5 Instrument Calibra7on
Sensor gain correc7ons based on ICM calibra7ons are applied to Edi7on1 data products.
CERES Instrument Working Group
ICM calibra7ons show a response increase of 0.4% for Total, 0.5% for Window sensor and a drop of 0.2% in SW sensor. Sensor response trends from solar calibra7ons are within +/-‐ 0.5%.
S-‐NPP/CERES FM5 Instrument Calibra7on
CERES Instrument Working Group
Comparison of calibra7on results from SWICS and MAM show similar trends in the SW sensor.
Suomi NPP/CERES FM5 Valida7on Results
CERES Instrument Working Group
Tropical Mean (TM): Monthly average of LW radiance for Tropical All-sky Ocean in +/- 20 degree latitude band. Day-Night Difference comparison between measured LW and Window measurements highlight changes in SW/TOT channel. Three Channel comparison use Deep Convective Cloud (DCC) as target. Trend in monthly slope between delta LW and SW measurements.
CERES S-‐NPP/FM5 – Aqua/FM3 Comparison
CERES Instrument Working Group
Tropical Mean LW comparisons show stable results. Global Flux Differences show that CERES FM5 SW measurements are higher and LW measurements lower than FM3 measurements.

FM1 – 5 INSTRUMENT SUMMARY
CERES Instrument Working Group
• Valida7on results from the Edi7on-‐4 datasets do not show trends in ocean and land scenes for Terra and Aqua SW and LW-‐day measurements.
• CERES FM5 calibra7on results show the performance trends are within expected range. SW sensor results are consistent between SWICS and MAM calibra7ons.
• S-‐NPP/FM5, Aqua/FM3 and Terra/FM1 comparisons are performed to evaluate whether there is any observed trends in FM5 measurements.
• The anomaly trends from Terra, Aqua and S-‐NPP show consistent results.
