| Zusammenfassung |
| We present a global and regional multi-annual (June 1996–May 2003) analysis
of cloud properties (spherical cloud albedo – CA, cloud optical thickness – COT
and cloud top height – CTH) of optically thick (COT > 5) clouds,
derived using measurements from the GOME instrument on board the ESA ERS-2
space platform. We focus on cloud top height, which is obtained from
top-of-atmosphere backscattered solar light measurements in the O2
A-band using the Semi-Analytical CloUd Retrieval Algorithm SACURA. The
physical framework relies on the asymptotic equations of radiative transfer.
The dataset has been validated against independent ground- and
satellite-based retrievals and is aimed to support trace-gases retrievals as
well as to create a robust long-term climatology together with SCIAMACHY and
GOME-2 ensuing retrievals. We observed the El Niño-Southern Oscillation
anomaly in the 1997–1998 record through CTH values over the Pacific Ocean.
The global average CTH as derived from GOME is 5.6 ± 3.2 km, for a
corresponding average COT of 19.1 ± 13.9. |
