2026-05-15 Dataset of Ku-band Geophysical Model Function Modeling at Low Incidence Angles Based on CFOSAT/SWIM doi:10.57760/sciencedb.37329 en The microwave spectrometer (Surface Waves Investigation and Monitoring, SWIM) carried on the China France Oceanography Satellite (CFOSAT) can measure the backscattering coefficient of the global sea surface under small incident angle conditions. This dataset is based on SWIM backscatter observation data from August 2022, combined with wind field observation data from the China France Marine Satellite Microwave Scatterometer (CSCAT), buoy wind field observation data, and related auxiliary analysis data. The backscattering coefficient wind field relationship in the range of 5-11 ° incidence angle and 0-20m/s wind speed is modeled, and the corresponding Geophysical Model Function (GMF) table is obtained. The dataset mainly includes a linear form of GMF result table, the boxwise average data used for modeling and fitting, and an example dataset. The GMF result table is located in the \ GMF \ RESULTS directory, and the average data of the sub boxes is located in the \ GMF \ RESULTS directory, both stored in. nc format files. The data corresponds to an effective incident angle range of 5-11 ° with an interval of 1 °, an effective wind speed range of 0-20m/s with an interval of 0.2m/s, an effective azimuth range of 0-180 ° with an interval of 2.5 °.  Geophysical model function; Backscattering coefficient; SWIM Dong Ziming PUBLIC https://creativecommons.org/licenses/by-nc/4.0/ dataset Science Data Bank
