This dataset is created using the τ-ω The model is obtained by combining TB inversion obtained by microwave imaging radiometer (MIRAS) of European Space Agency (ESA) SMOS mission in H and V polarization L-band (1.4 GHz). Apply threshold and 2-sigma standard on TB to filter invalid data. The RFI flag based on the modeling method of these interferences is used to shield the polluted pixels. Because the resolution of SMOS data is relatively coarse (between 25 and 60 kilometers), the soil and vegetation within a pixel are uneven. TB per pixel is the weighted total scattering of each vegetation and soil type coverage. The data has a spatial resolution of 25 - km and a temporal resolution of 1 day.
The name of the file is "SM_OPER_MIR_CLF31x_yyyymmddThhmmss_YYYYMMDDTHHMMSS_vvv_ccc_n", in "CLF31x", x represents the lift rail, "A" represents the lift rail, "D" represents the drop rail, and "yyyymmddThhmmss" represents the start time of the data contained in the product
