ACOS GOSAT v9 Super Lite XCO2 data

Only the most essential variables for each satellite observation are preserved in these "superlite" files: latitude and longitude (both at the surface viewing location), the unique sounding identification number (format is: 4 digit year, 2 digit month, 2 digit day, 2 digit hour, 2 digit minute, 2 digit second), and the estimated dry-air mole fraction of total column carbon dioxide in parts per million.

The monthly files also contain the set of operational L2FP "lite" files from which the data was extracted, and which can be downloaded from the NASA Goddard Earth Sciences (GES) Data and Information Services Center (DISC) (10.5067/VWSABTO7ZII4). This superlite "teaser" product is a companion to the recently published journal article "An eleven year record of XCO2 estimates derived from GOSAT measurements using the NASA ACOS version 9 retrieval algorithm" in Earth System Science Data by T.E. Taylor, et al. (doi.org/10.5194/essd-2021-247) It is meant to provide entry level users with a light weight satellite product for initial exploration.
