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.
Lothar Schueller gives an overview on the SAF structure and the generated products.
Length: 30 minutes.
SAFs are dedicated centres of excellence for processing satellite data, achieved by utilising specialist expertise from the Member States. SAFs generate and disseminate operational EUMETSAT products and services and are an integral part of the distributed EUMETSAT Application Ground Segment.
Each SAF is led by the National Meteorological Service (NMS) of a EUMETSAT Member State, in association with a consortium of EUMETSAT Member States and Cooperating States, government bodies and research institutes. The lead NMS is responsible for the management of each complete SAF project. The research, data and services provided by the SAFs complement the standard meteorological products delivered by EUMETSAT’s central facilities in Darmstadt, Germany.
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.
Nigel Atkinson from the UK MetOffice presents the AAPP package to process ATOVS and AVHRR data. Some processing and visualisation examples are given.
The ATOVS and AVHRR Pre-processing Package (AAPP) is a tool to process sounder and imager data from the NOAA, Metop and FengYun polar orbiting satellites. It was originally developed in the late 1990s to support processing of direct broadcast data from the NOAA-POES satellites, and has since been extended to accommodate Metop (including IASI) and more recently Suomi-NPP. The package is maintained by the EUMETSAT Satellite Application Facility for Numerical Weather Prediction (NWP SAF). An overview will be given of the capabilities of AAPP, including how it complements other processing packages such as IMAPP and CSPP. AAPP products include calibrated, re-mapped radiances (for NWP) and derived products such as cloud mask. Examples of the products and their uses will be shown.

Trained at Queen's University as a nuclear physicist, "Phil the Forecaster" has been a professional meteorologist since 1976. Officially retired in 2011 Phil still continues to advance his research efforts with COMET and the Meteorological Service of Canada (MSC). Satellite and radar meteorology are his forte. Much of this research has been published by COMET under the Satellite Palette banner. Phil has also completed original and extensive research on performance measurement. This large body of work resides in the Case Studies section of Northern Latitude Meteorology (NorLatMet/COMET). Aside from the above Phil has been painting en plein air forever - Philtheforecaster.blogspot.com - art and science are indeed similar endeavours. A sense of humour bundles all of this together and makes learning and teaching fun.

The Rapidly Developing Thunderstorm product provides in object-mode information about significant convective systems. Various attributes describe the convective system: cloud-top temperature and height, overshooting tops, morphological attributes. The product uses the satellite brightness temperature of various channels and optional data like NWP data, lightning data and other NWCSAF products. A nowcast of convective systems is developed for 2016.
A new NWCSAF product (Convection Initiation – the probability of a cloudy pixel to become a thunderstorm) will be developed for 2016.
