In October 2020, all 3-hourly and monthly GLDAS-2 data were post-processed with the MOD44W MODIS land mask. Previously, some grid boxes over inland water were considered as over land and, thus, had non-missing values. The post-processing corrected this issue and masked out all model output data over inland water; the post-processing did not affect the meteorological forcing variables. More information can be found in the GLDAS-2 README
. The MOD44W MODIS land mask is available on the GLDAS Project site
If you downloaded the GLDAS data prior to November 2020, please download the data again to receive the post-processed data.
The 0.25-degree 3-hourly variables in Giovanni are still being updated with the post-processed data; the projected completion dates are around the middle of December 2020 for GLDAS-2.1 and around the end of February 2021 for GLDAS-2.0.
