Dear EARTHDATA FORUM,
recently I downloaded OMI AOD daily data from GIOVANNI, but the results are not quite good. The result shows some days had so many decimal places eg.-1.267651E+30.
I am still trying to figure out the source of this issue, or is it still
a good data that I should use or discard them, but they are many.
Any assistance, please.
Thank you.

OMI Aerosol optical depth data from Giovanni
Thank you for your interest in our data and services.
When you download comma-separated value (CSV) files, you will find a line like this:
Fill Value (mean_OMAERUVd_003_FinalAerosolOpticalDepth500):, -1.267651e+30
that appears near the beginning of the file, before the data values for the variable. This indicates that all occurrences of -1.267651e+30 are to be treated as a fill value, and should be omitted from your data analysis. A fill value indicates that there were no data values available for that date in the geographic region that you specified, and the values have a large magnitude to make it easier to clearly distinguish them from values where data were available.
