全球0.25°CCMP海面风场逐月数据集（1987.07-2019.04）

"该数据集中的数据获取自美国“遥感系统”（Remote Sensing System,RSS）研制发布的CCMP数据集，包括1987.07-2019.04逐月0.25°分辨率风场nc数据，数据总体量为3.87G。
CCMP 数据集使用变分分析方法 (VAM) 结合了交叉校准的卫星微波风和仪器观测，以产生高分辨率（0.25 度）网格分析。使用由遥感系统从许多星载无源和有源微波仪器中获得的卫星风反演。RSS 将亮度温度水平的辐射计相互校准到 0.2 摄氏度以内，应用改进的海面发射率模型和辐射传递函数来推导地表风。VAM 将 RSS 仪器数据与系泊浮标测量和风场的初始估计（初步猜测）相结合。欧洲中期天气预报中心 (ECMWF) ERA-Interim Reanalysis 风在 CCMP V2.0 处理中用作初步预测风场。"

The data in this dataset is sourced from the CCMP dataset developed and released by the Remote Sensing System (RSS) of the United States. It includes monthly 0.25° resolution wind field data in netCDF (.nc) format spanning from July 1987 to April 2019, with a total data volume of 3.87 GB.
The CCMP dataset adopts the Variational Analysis Method (VAM) to combine cross-calibrated satellite microwave wind data and in-situ observations, generating high-resolution (0.25°) grid analyses. Satellite wind retrievals derived by RSS from numerous space-borne passive and active microwave instruments are utilized in this process.
RSS calibrates radiometers at the brightness temperature level to within 0.2 degrees Celsius, and applies improved sea surface emissivity models and radiative transfer functions to retrieve surface winds.
The VAM integrates RSS instrument data with moored buoy measurements and initial wind field estimates (first-guess values).
The European Centre for Medium-Range Weather Forecasts (ECMWF) ERA-Interim Reanalysis winds serve as the first-guess wind fields during the CCMP V2.0 processing.
