1.0 Data Set Description

Introduction or abstract:
The cloud products are subsetted from global, 3-km resolution gridded data. The satellites involved include: Terra, Aqua MODIS; N20 VIIRS; GOES-16 ABI, Meteosat-10 SEVIRI.
Data version number and date: v01a
Data Status: Preliminary (not publication-ready) 
Time period covered by the data: 02/20/2024-04/13/2014
Physical location (including lat/lon/elev) of the measurement or platform: Earth Orbit
Data Frequency - Hourly
Data source: GOES-16 ABI, Meteosat-10 SEVIRI, Terra, Aqua-MODIS, N20-VIIRS
Web address references: https://satcorps.larc.nasa.gov/indexV2.html
Data set restrictions: None


2.0 Instrument Description

The instruments are from satellite passive radiometers: MODIS-1km, VIIRS-1km, ABI-2km, SEVIRI-3km

3.0 Data Collection and Processing

Description of data collection:
Data were collected from McIDAS ADDE servers at Univ. Wisc SSEC Data Services

Description of derived parameters and processing techniques used
The composites were derived using the best satellite view angle and time match to the top of hour nominal image time.

Description of quality assurance and control procedures:
Processing was checked for large percentage of non-valid data and was rerun if possible

Data intercomparisons, if applicable
None
