Pieter Groenemeijer (ESSL) presents his findings in using low-level moisture proxy data from polar orbiting satellites at European Severe Storms Laboratory training events.
In preparation for MTG data, ESSL is carrying out a series of expert workshops and Testbeds in collaboration with EUMETSAT. At both event types, the increased capabilities of detecting low-level moisture from geostationary orbit, which the MTG program will enable, have received a high amount of attention. In our presentation, we will discuss a number of convective storm cases that were studied using proxy data from polar-orbiting instruments, such as MODIS. One of the ways to visualize low-level moisture is by depicting the ratio of the 0.91 and 0.85 μm channels with an intuitive color scale. We will discuss to what extent this and other proxies for low-level humidity can be used to anticipate the presence of a crucial ingredient for severe deep, moist convection...
Wilfried Jacobs (DWD) introduces the water vapour channels in the 2022 EUMeTrain Water Vapour Event Week.
The target group of this presentation is participants that are not familiar or do not feel familiar enough for understanding the presentations during the entire week. The first presentation deals with basics of vapour water channels in satellite products. First, the principle of radiation and radiation transfer will be outlined briefly and put in relation to wave lengths of imagers and vertical sounders by considering weighting functions. The second part deals with some examples by using single channels. Finally, corresponding composites (RGBs) and their applications will explained in detail.
Mary Forsythe presents the impact of satellite winds on the performance of NWP models (ECMWF).
Satellite-derived winds are an important part of the global observing system. Atmospheric motion vectors, derived from tracking clouds in satellite imagery, and ocean surface winds from scatterometers have been routinely assimilated in global and regional NWP models for many years. More recently, wind profiles have become available from the Aeolus Doppler Wind Lidar. The talk will focus on how we use these datasets, their impact in global NWP models and some thoughts for the future.
Ralf Bennartz from the University of Wisconsin gives an introduction on the principles of atmospheric soundings with AIRS and AMSU sensors.
High resolution infrared sounders, such as AIRS and IASI, and microwave sounders, such as AMSU, are a key element of the global satellite observing system and provide a wealth of data important for various operational applications including data assimilation and nowcasting applications. This presentation will revisit the physical basis of infrared and microwave sounding and provide an overview on the state-of-the-art of microwave and infrared soundings.
Tony McNally from ECMWF speaks about data assimilation of polar orbiting satellites. He gives an insight into the methods used and accentuates the benefits of satellite data in general for the forecast skills.
This lecture introduces the central role played by data assimilation in Numerical Weather Prediction, Climate Reanalysis and Environmental monitoring. It will be shown that radiance observations from polar orbiting satellites are the single most influential component of the global observing network and the impact of these data on forecast quality will be demonstrated. Finally, the major scientific challenges facing the successful exploitation of satellite radiance observations will be discussed - in particular issues related to vertical resolution, cloud and precipitation contamination and systematic errors.
