| Abstract: | One-dimensional retrieval was performed on Typhoon Haiyan utilizing the advanced technology microwave sounder onboard the satellite Suomi NPP to retrieve the temperature and water vapor profiles of the typhoon. Comparisons of the retrieved profiles and ECMWF reanalysis were made to assess the results. The main conclusions are as follows. (1) The results have high spatial resolution and therefore can precisely represent the temperature and humidity distribution of the typhoon. (2) The retrieved temperature is low in the areas of low temperature and high in the areas of high temperature; similar patterns are observed for humidity. This means that systematic revision may be needed during routine application. (3) The results of the retrieved temperature and humidity profiles are generally accurate, which is quite important for typhoon monitoring. |
