I am using the M2I6NPANA product to obtain air temperature data for different pressure levels in South Asian countries. I have seen corresponding values for most regions, but have encountered some NA/NaN values in some places. I tried to see if this was documented in the FAQs and other notes, but I could not find them.
Could you please guide me to the appropriate answers if already documented, or tell me what would be the causes of producing NA values?
MERRA-2 has not extrapolated data beneath the surface. The result is that
lower pressure levels, such as 1000, 925, and 850 hPa may consist of missing
data if it is below the surface. More information can be found in the FAQ of
the MERRA-2 project page :
