This study provides a comprehensive overview of the temperature and zonal wind biases in eight reanalysis data products, with a focus on stratospheric levels. The study identifies biases in each reanalysis from the “reanalysis mean” (defined as the mean of the MERRA, ERA-Interim, and JRA-55 reanalyses). It then examines reanalysis temperature biases with respect to HIRDLS (an independent satell...

With the establishment of a new High Resolution Picture Transmission (HRPT) reception system at IMD, New Delhi, real time data from microwave sounding instruments onboard NOAA-K, L, M and N series satellites has also become available. The raw HRPT is being interfaced with recently acquired ‘ATOVS AVHRR Preprocessing Package (AAPP)’ to perform temperature moisture retrievals AMSU NOAA-16 satelli...
