This dataset contains derived satellite observations of cloud properties over the Australian region at hourly temporal resolution and 2 km spatial resolution. The Himawari-8 CSPPGeo Geocat collection Level-2 (L2) grid is on 2 km of horizontal resolution that includes Australia and the Maritime Continent. The L2 product include full output variables from CSPP-Geo Geocat and Advance Himawari Imagery on Himawari-8, 25, and 41 variables, respectively, with hourly temporal resolution for Austral summer months (Nov-March) from 01 November 2015 to 31 March 2020.

NB Some images were not available for processing at the time of the dataset release, we listed all the missing timesteps in the file L2_file_gaps_20210225.txt

More images might become available and then new lists will be created accordingly with the timestamp indicating when the files where added.

We ask users to specify the date they access the datasets when they cite them as indicated in the citation field.
