GRACE 'months'
Generation of a good gravity field solution requires accumulation of satellite-to-satellite tracking data for about 1 month. The data we give here are labeled by their nominal month (consecutive since 1/1/2002=1). We list the actual data dates (start, end, and missing) over which data were collected corresponding to the nominal month. Within that month, a few days of data may not be used due to instrument. The 'Common' missing days are missing in solutions from all 3 centers; the last 3 columns indicate additional days missing from that center's solutions.
