Questions about CERES GEO dataset.

by imnbakerstreet » Tue May 07, 2024 4:09 am America/New_York

What's the difference of version 1.0 and version 1.2 in some satellites of the CERES GEO dataset? Such as GOES-15 and GOES-13.

I also notice that the version always changes in 2015 and there are some overlapping periods in two versions. Which version shoud be used in the overlapping periods?

There is a limitation in our processing code that requires that all five geostationary satellite have the same version. We needed to reprocess data for the Himawari 8 starting in July 2015 that necessitated the change. The overlap period was what was processed before the need was discovered. We are currently working to clean up the overlap period.

For the GOES-13 and GOES-15, there is no difference between the two files.

The higher version should be used, i.e. 1.2, when available.
