Geostationary Satellite Retrievals with Irradiances and Cloud Properties / Processed Data

The Geostationary Operational Environmental Satellite (GOES) records sky brightness temperatures and irradiances at several wavelengths. From these the cloud microphysical and optical properties can be routinely retrieved. These properties are derived using the technique proposed by Minnis et al. 2020, and is similar to the technique used for deriving cloud properties from Moderate Resolution Imaging Spectroradiometer (MODIS) data. The derived GOES properties for the duration of the second Wind Forecasting Improvement Project (WFIP2) within the domain are reported here. Nominally the retrieved dataset has a 30- minute temporal and a 9 km spatial resolution.

地球静止轨道运行环境卫星（Geostationary Operational Environmental Satellite, GOES）可在多个波段记录天空亮温与辐照度。基于此类观测数据，可常规反演云的微物理与光学特性。此类特性的反演采用了Minnis等人2020年提出的方法，该方法与从中分辨率成像光谱仪（Moderate Resolution Imaging Spectroradiometer, MODIS）数据中反演云特性的技术思路相近。本文公开了该研究区域内第二次风能预报改进项目（Wind Forecasting Improvement Project, WFIP2）实施期间反演得到的GOES云特性数据集。该反演数据集标称时空分辨率分别为30分钟与9千米。
