Clouds Data

GLOBE Clouds and Matched Satellite Data

When a GLOBE Clouds observation is taken within 15 minutes of a satellite overpass, the data are matched to NASA satellite data for further analysis. The GLOBE Clouds data and matching satellite data are provided as CSV files for the period named. These data files include all clouds data received by GLOBE and matched to satellite data by the NASA Langley Research Center GLOBE Clouds team as of the date in the file name (example: 2017_GLOBE_cloud_data_2020-01-13_v1-1.csv). Version 1.1 includes all data from Version 1.0, plus data that was received after the Version 1.0 files were generated.
