AMSR-E/aqua daily gridded brightness temperatures of China-National Tibetan Plateau Data Center

This dataset includes passive microwave remote sensing brightness temperatures data for longitude and latitude projections and 0.25 degree resolution from 2002 to 2008 in China.

1. Data processing process:

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. Data format:

Brightness temperature files: two-byte unsigned integers, little-endian byte order

Time files: two-byte signed integers, little-endian byte order

3. Data naming:

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)

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)
