Use of Spectral Information in the Microwave Region for Numerical Weather Prediction Data Assimilation
In the last decades, the performance of numerical weather prediction models has significantly improved due to the assimilation of satellite data, and these data have become an indispenible part of the weather forecast.
In parallel, the detectors used in the microwave region have undergone a rapid development and now new spectral regions and channel set ups can be used by satellite instruments, that were not accessible earlier mainly due to technical limitations.
We present a study where regions in the spectral range from 1 to 1000 GHz were examined with the aim to obtain an overview on possible new spectral regions and channels for future satellite instruments. For this aim, channels with sensitivity to various atmospheric parameters as well as in the spectral windows region were selected. The channels were selected both at new positions, and at positions already used by sensors but using modified channel characteristics. Their influence on the performance of NWP models has been assessed. The overall goal of this study is to provide a basis for the development of future meteorological satellite instruments.
