Data discrepency between CERES and ERA5

by grayshoe » Tue Mar 01, 2022 10:02 pm America/New_York

I am trying to use hourly CERES radiation data, along with hourly ERA5 precipitation data. While I was working on temporally synchronizing both data, I've noticed that the CERES TOA incoming solar radiation does not align with that of the ERA5. If you look at the attached images, the CERES maximum TOA incoming solar radiation region is in the center of the domain, whereas ERA5 is at the edge of the domain. Their time difference is only 30 minutes, yet it looks like their difference is more like 12 hours. Why is this?

Sorry for the lines in the image, I guess screen shot by selecting a region made those lines on the map.

Nevermind. It was my mistake. They are very similar. I was confused by the difference of longitude orientations of both datasets.
