英文摘要 | Large-scale satellite data are critical for both verifying and improving general circulation model parameterizations of clouds and radiation for climate prediction. For reliable application of satellite data sets in cloud processes and climate models, it is important to have a reasonable estimate of the errors in the derived cloud properties. The daytime single-layered low-level cloud properties retrieved by the Geostationary Operational Environmental Satellite system (GOES) are compared with ground-based observations and retrievals over the Department of Energy Atmospheric Radiation Measurement (ARM) Southern Great Plains (SGP) Central Facility from June 1998 to December 2006. The GOES retrievals are made via the Visible-Infrared Solar-infrared Split-window Technique. They are spatially averaged within a 0.15 degrees x 0.15 degrees box centered on the ARM SGP site, and the ARM surface observations are temporally averaged +/- 15 min around the GOES scans to produce collocated pairs. Comparisons are made for monthly means, diurnal means, and one-to-one GOES and ARM collocated pairs. GOES T-eff is highly correlated with ARM T-top cloud temperature, having an R-2 value of 0.75, though GOES exhibits a cold bias. GOES-retrieved tau and liquid water path have very good agreement with ARM retrievals with R(2)s of 0.45 and 0.47, while r(e) (GOES), on average, is about 2 mu m greater than ARM r(e). An examination of solar and viewing geometry has shown that GOES-retrieved mean r(e) and tau values are impacted by solar zenith angle and especially scattering angle, which is not unexpected and needs to be accounted for by users. |
