In this study, an atmospheric phenomenon, land breeze system, was observed on one image mode high resolution SAR image and one middle resolution optical image. WRF model was implemented with actual meteorological conditions as inputs to successfully simulate this process with some understandable discrepancies. The overpass time of ASAR and MODIS are at 10:35 AM and 11:10 AM local time in Hainan. Long...
<?Pub Dtl?>Geophysical model functions (GMFs) for deriving sea surface wind from C-band synthetic aperture radar (SAR) are usually developed and well validated for VV-polarized data, e.g., CMOD5. For wind retrievals from HH-polarization data acquired by some SAR satellites, e.g., RADARSAT-1, part of RADARSAT-2 and ENVISAT ASAR, various Polarization Ratio (PR) models are used to convert normalized...
Marine atmospheric boundary phenomena, i.e., atmospheric gravity waves (AGW), vortex streets and boundary rolls, modulate the surface wind field and will leave imprints visible on synthetic aperture radar (SAR) images. In this case study, we present an ENVISAT SAR observation of AGW offshore of the mountain Laoshan along the yellow sea coast of China. The Weather Research and Forecasting (WRF) weather...
High spatial resolutions synthetic aperture radar (SAR) retrieved ocean surface wind field under actual conditions can be affected by several ocean surface features, such as artificial object, surface oil slicks and air-sea boundary layer stabilities etc. In this paper we present several case studies of those impacts, and a semi-empirical model to correct the air-sea boundary layer stabilities. We...
