Getting the size of a file via API

Is there any way to determine the byte size of a file on your data server using the file_search, getfile or other cgi tools?We have cases where we want to ignore files below a certain size. It would also be nice to compare the remote and local file sizes to verify that the file wasn't truncated....

getfile not working

Brock,

It looks like the download issue you're seeing is affecting everything not just the ancillary data.

On a whim I checked our other subscriptions (which are all for L2 data). It looks like we stopped downloading any new data between 15:00 and 17:00 UTC yesterday (8/8).

Pixel day/night determination within SST L2

If I have an L2 SST granule with the day_night_flag set to "Mixed", is there a method to determine which pixels within the granule are day vs night vs dusk?

Is the answer any different for VIIRS NPP vs VIIRS N20 vs MODISA?

Cloud flagging adjustments

Sean,Thank you, as always, for your helpful hints. I tried with the straylight flag and while it removed almost all of the cloud contamination (yaay!) it also dropped more pixels than we would like :(.You said the flag is based on reflectance at 869nm - is that rrs_869, rhos_869, the cloud_albedo pr...
