Description
Lookup tables for estimating the cloud-top height (CTOP) and visible optical thickness of uppertropospheric clouds by the infrared brightness temperature (TB) at 10.8 μm (T11) and its difference from TB at 12 μm (DT11-12) measured by geostationary satellites are developed (Hamada and Nishi 2010, JAMC). These lookup tables were constructed by regressing the cloud radar measurements by the CloudSat satellite over the infrared measurements by the Japanese geostationary multifunctional transport satellite MTSAT-1R and MTSAT-2. The CTOP is available at http://database.rish.kyoto-u.ac.jp/arch/ctop/ since July 2005. The data have good precision for cirrus clouds (τ > ~3) that have large DT11-12 values and are suitable for analyses of cloud systems with well-developed cirrus clouds. We made correction for the satellite view angle and can offer the data over almost all tropical regions where the satellites can observe (20S-20N, 80E-160W for MTSAT-1R and 85E-155W for MTSAT-2).
