IASI-FT Skin Temperature (from IASI/Metop-C)

IASI Skin Temperature is a monthly (L3), 1x1 degree global dataset of skin temperatures over land derived from the IASI satellite radiances data. The dataset consists of monthly mean TXT files. Each file is a grid organized by latitude (-90 to 89 °N) and longitude (-180 to 180 °E). Night and day data are separated based on the local time of IASI's overpass at each grid point. The sea grid points are filled using NaN. Size of the grid : 180 lines and 361 columns. Separator : comma. Unit : degree Celsius.

IASI地表皮肤温度（IASI Skin Temperature）数据集是基于IASI卫星辐射数据反演得到的全球陆面皮肤温度月度L3级数据集，空间分辨率为1×1度。该数据集由月度平均TXT文件构成，每个文件为按纬度（-90°至89°N）与经度（-180°至180°E）组织的网格数据。日间与夜间数据依据IASI卫星在各网格点的过境当地时间进行区分，海洋网格点以NaN值填充。网格尺寸为180行、361列，数据分隔符为逗号，单位为摄氏度。
