Measurements
ATSR / AATSR
Local Observation Time and Length of Data Record
10:00 AM ; 1999-2002 (ERS), 2003-2009 (Envisat)
Spatial Resolution
1 km (detection), 4 km (retrieval)
Cloud Detection
VIS/NIR/IR optimal estimation.
Retrieval Methodology
COD, CP, CRE, phase -> CT, CWP.
Cloud pressure, cloud optical depth, and effective particle radius are retrieved only during day,
using an Optimal Estimation approach on the five available VIS / NIR / IR channels (0.7, 0.9, 1.6, 11, and 12 μm).
Cloud water path is derived from optical depth and effective particle radius.
