Abstract:
Using Weather Research and Forecasting (WRF) to simulate water vapor is one of the efficient and reliable methods of current InSAR atmospheric correction. However, its preprocessing is complicated and requires a higher computing environment, and its running time is longer. The above-mentioned characteristics limit the use of WRF. Different initializations have a non-negligible impact on the running time and simulation results. We use ERA5 and FNL to drive WRF to simulate water vapor and the results are used for tropospheric correction in the Beijing region. The comparative evaluation with MERIS and GACOS proved the reliability of WRF with ERA5 as the initialization for InSAR atmospheric correction. The high time resolution of ERA5 effectively shortens the simulation time of WRF and provides the possibility for its atmospheric correction application in time series InSAR.
