本数据集包括中国地区2002-2008年,经纬度投影,0.25度分辨率的被动微波遥感亮度温度数据。 1、数据处理过程: NSIDC produces AMSR-E gridded brightness temperature data by interpolating AMSR-E data (6.9 GHz, 10.7 GHz, 18.7 GHz, 23.8 GHz, 36.5 GHz, and 89.0 GHz) to the output grids from swath space using an Inverse Distance Squared (ID2) method。 2、数据格式: Brightness temperature files: two-byte unsigned integers, little-endian byte order Time files: two-byte signed integers, little-endian byte order 3、数据命名: ID2rx-AMSRE-aayyyydddp.vnn.ccc(China-ID2r1-AMSRE-D.252002170A.v03.06V) ID2 Inverse Distance Squared r1 Resolution 1 swath input data AMSRE Identifies this an AMSR-E file D.25 Identifies this as a quarter degree file yyyy Four-digit year ddd Three-digit day of year p Pass direction (A = ascending, D = descending) vnn Gridded data version number (for example, v01, v02, v03) ccc AMSR-E channel indicator: numeric frequency (06, 10, 18, 23, 36, or 89) followed by polarization (H or V) 4、切割范围: Corner Coordinates: Upper Left ( 60.0000000, 55.0000000) ( 60d 0'0.00"E, 55d 0'0.00"N) Lower Left ( 60.0000000, 15.0000000) ( 60d 0'0.00"E, 15d 0'0.00"N) Upper Right ( 140.0000000, 55.0000000) (140d 0'0.00"E, 55d 0'0.00"N) Lower Right ( 140.0000000, 15.0000000) (140d 0'0.00"E, 15d 0'0.00"N) Center ( 100.0000000, 35.0000000) (100d 0'0.00"E, 35d 0'0.00"N) Origin = (60.000000000000000,55.000000000000000) 5、数据投影: GEOGCS["WGS 84", DATUM["WGS_1984", SPHEROID["WGS 84",6378137,298.257223563, AUTHORITY["EPSG","7030"]], TOWGS84[0,0,0,0,0,0,0], AUTHORITY["EPSG","6326"]], PRIMEM["Greenwich",0, AUTHORITY["EPSG","8901"]], UNIT["degree",0.0174532925199433, AUTHORITY["EPSG","9108"]], AUTHORITY["EPSG","4326"]]
