The radiation at Lband has a good linear relation with the bright temperature.
波段微波辐射值和根据辐射理论计算出的亮温值具有很好的线性关系。

The International Telecommunications Union reserves a special radio band in the 1400-1427 MHz range, called the L-band, especially for Earth-observing satellites and space astronomy.
Even though the window at L-band is the best choice for salinity remote sensing, the sensitivity of brightness temperature to SSS is lower than that of the other variables.
