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)
