The GOZCARDS Source Data for Nitrous Oxide 1 month L3 10 degree Zonal Averages on a Vertical Pressure Grid product (GozSmlpN2O) contains zonal means and related information (standard deviation, minimum/maximum value, etc.), calculated from original Level 2 satellite instruments and products. The source N2O data are from the following satellite instruments: ACE-FTS (v2.2; 2004-onward) and Aura MLS (v2.2; 2004 onward). The vertical pressure range for N2O is from 147 to 0.5 hPa. The source data are used to create a merged product contained in a separate data product with the short name GozMmlpN2O. The GozSmlpN2O source data are distributed in netCDF4 format.
