Level 3C/3S of AVHRR (NOAA15-18), MODIS (Aqua, Terra), AATSR (ENVISAT), and MERISAATSR (ENVISAT)

Description
Cloud properties combined (averaged) from a single instrument into a global space-time grid.
- Spatial resolution: 0.5° lat/lon
- Temporal resolution:
1 month
- File format: netcdf 3, CF standard v1.5

 

 

Level 3U of AVHRR (NOAA16,18), MODIS (Aqua, Terra), AATSR (ENVISAT), and MERISAATSR (ENVISAT):

Description

Cloud properties of L2 data granules remapped to a global space grid without combining any observations from overlapping orbits. Only sampling is done. Common notation for this processing level are also L2b and L2G.
- Spatial resolution: 0.1° lat/lon
- Temporal resolution:
1 day
- File format: netcdf 3, CF standard v1.5


 

Examples of Level 2 of AVHRR/NOAA-18 (Round Robin dates)::

(for more other Level 2 data, please contact contact.cloudcci (at) dwd.de)

Description
Retrieved cloud variables at the same resolution and location as the level 1 source.
- Spatial resolution: approx. 5km
- Temporal resolution: approx.
2 overpasses per satellite and day for non-polar regions
- File format: netcdf 3, CF standard v1.5
