GSICS Correction Algorithm for Geostationary Infrared ImagersThe first major deliverable to the user community is the GSICS correction algorithm for geostationary satellites.

The user applies the correction to the original data using GSICS provided software and coefficients. Before 3K Bias

The correction adjusts the GOES data to be consistent with IASI and AIRS.

The figures to the left show the difference between observed and calculated brightness temperatures (f NCEP l i ) b f d ft ti(from NCEP analysis) before and after correction

The bias is reduced from 3 K to nearly zero. After: ~ 0K Bias

GPRCs have their own product monitoring/plotting websites “GSICS Plotting Tool” has been developed at EUMETSAT

• Common look and feel (Easy comparison among multiple products)• Dynamical plotting (no need to prepare lots of figures)• Now, only single file is supported (i.e., RAC which contains all time series info.)

GSICS Principles

• Systematic generation of inter‐calibration products• for Level 1 data from satellite sensors• to compare, monitor and correct the calibration of monitored instruments to community references

TRACEABILITY / UNBROKEN CHAINS OF

• by generating calibration corrections  on a routine operational basis• with specified uncertainties• through well‐documented, peer‐reviewed procedures

COMPARISONS

• based on various techniques to ensure consistent and robust results

• Delivery to users• Free and open accessp• Adopting community standards

• To promote• Greater understanding of instruments’ absolute calibration• Greater understanding of instruments  absolute calibration, by analysing the root causes of biases

• More accurate and more globally consistent retrieved L2 products• Inter‐operability for more accurate environmental climate and weather forecastingInter‐operability for more accurate environmental, climate and weather forecasting products

Who are the targeted users?

Any activity requiring well calibrated Level 1 data acquired by the satellites covered by

GSICS- Level 2 products (geophysical parameters)- Climate applications

Example of user = the SCOPE-CM initiative (Sustained Coordinated Processing of Environmental Satellite Data for Climate Monitoring)
