WATER: Dataset of airborne microwave radiometers (L&K bands) mission in the A'rou-Biandukou flight zone on Mar. 19, 2008 Chinese Version


The dataset of airborne microwave radiometers (L&K) mission was obtained in the A'rou-Biandukou flight zone on Mar. 19, 2008.

The frequency of L bands was 1.4 GHz with back sight of 35 degree and dual polarization (H&V) was acquired; and the frequency of K band was 18.7 GHz at the nadir view angle without polarization. The plane took off at Zhangye airport at 9:25 (BJT) and landed at 12:50 along the scheduled lines at the altitude about 4100m and speed about 260km/hr.

The raw data include microwave radiometer (L&K bands) data and GPS data; the former are instantaneous non-imaging observation recorded in text, which will be converted into brightness temperatures according to the calibration coefficients (filed with raw data together), and the latter are aircraft longitude, latitude and attitude. Moreover, based on the respective real-time clock log, observations by the microwave radiometer and GPS can be integrated to offer coordinates matching for the former. Yaw, flip, and pitch motions of aircraft were ignored due to the low resolution of microwave radiometer observations. Observation information can also be rasterized, as required, after calibration and coordinates matching. L&K bands resolution (x) and footprint can be approximately estimated as x=0.3H (H is relative flight height) for L band and x=0.24H for K band.
