The second edition of the satellite-derived climate data record
CLARA (<q>The CM SAF Cloud, Albedo And
Surface Radiation dataset from AVHRR data</q> – second edition
denoted as CLARA-A2) is described. The data record covers the 34-year period
from 1982 until 2015 and consists of cloud, surface albedo and surface
radiation budget products derived from the AVHRR (Advanced Very High
Resolution Radiometer) sensor carried by polar-orbiting, operational
meteorological satellites. The data record is produced by the EUMETSAT
Climate Monitoring Satellite Application Facility (CM SAF) project as part of
the operational ground segment. Its upgraded content and methodology
improvements since edition 1 are described in detail, as are some major
validation results. Some of the main improvements to the data record come
from a major effort in cleaning and homogenizing the basic AVHRR level-1
radiance record and a systematic use of CALIPSO-CALIOP cloud information for
development and validation purposes. Examples of applications studying
decadal changes in Arctic summer surface albedo and cloud conditions are
provided. |
