SMOS L3 Vegetation Optical Depth (VOD) Data Set in Southwest China (2010-2022)

This dataset is obtained through the inversion the TB acquired by Microwave Imaging Radiometer using Aperture Synthesis (MIRAS) on board the European Space Agency (ESA) SMOS mission at L band (1.4 GHz) at H and V polarizations, using the τ-ω model. Thresholds and 2-sigma criteria are applied on the TB to filter out invalid data. A RFI flag, based on a modelling approach of these interferences, is applied to mask the contaminated pixels. Due to the coarse resolution of the SMOS data (between 25 and 60 km), soil and vegetation are not uniform inside a pixel. Each pixel TB is the sum of the emission of each vegetation and soil type class weighted by its intra-pixel cover fraction. The data has a spatial resolution of 25 - km and a temporal resolution of 1 day.

File naming and required software

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
