The Satellite Application Facility for Land Surface Analysis hosted by the Portuguese Meteorological Institute in Lisbon generates and distributes value added satellite products for numerical weather prediction and environmental applications in near-real time. Within the project consortium Météo-France is responsible for the land surface albedo and down-welling short-wave radiation flux product...

Wind products from geostationary satellites have been generated for over 20 years and are now used in numerical weather prediction systems. However, geostationary satellites are of limited utility poleward of the midlatitudes. This study demonstrates the feasibility of deriving high latitude tropospheric wind information from polar-orbiting satellites. The methodology employed is based on the a...

Many plant disease outbreaks are triggered by suitably warm temperatures during periods of leaf wetness. Measurements or estimations of leaf wetness duration provided by Agrometeorologists have allowed Plant Pathologists to devise weather timed spray schemes which often reduce the number of sprays required to control plant diseases, thus lowering costs and benefitting the environment. In the ne...

Satellite estimates and weather forecast models have made it possible to observe and predict precipitation over large spatial scales. Despite substantial progress in observing patterns of precipitation, characterization of spatial patterns is still a challenge. Quantitative assessment methods for spatial patterns are essential for future developments in prediction of the spatial extent and patt...

Precooling a building overnight during the summer is a low cost practice that may provide significant help in decreasing energy demand and shaving peak loads in buildings. The effectiveness of precooling depends on the weather patterns at the location, however research in this field is predominantly focused in the building thermal response alone. This paper proposes an analytical tool for asses...

Mapping of the zenith hydrostatic delay at radio frequencies to elevations as low as 3° has been improved by making use of the in situ atmosphere state. This information might be obtained from a numerical weather model, thus providing better atmosphere calibration on a global scale. The new model has been evaluated by comparing the repeatability of the lengths of baselines measured by Very Long...

Numerous methods exist and were developed for global radiation forecasting. The two most popular types are the numerical weather predictions (NWP) and the predictions usingstochastic approaches. We propose to compute a parameter noted  constructed in part from the mutual information which is a quantity that measures the mutual dependence of two variables. Both of these are calculated with the ...

The forecast process within an operational weather centre is based upon the analysis, diagnosis and prognosis of skilled meteorologists. To aid their efforts, the forecasters use a wide range of tools including weather satellites, radar, workstations, and numerical weather prediction (NWP) models. Tremendous gains in NWP performance over the past 2 decades has made this tool typically the most ...

This paper addresses the issue of performing global sensitivity analysis of model output with dependent inputs. First, we define variance-based sensitivity indices that allow for distinguishing the independent contributions of the inputs to the response variance from their mutual dependent contributions. Then, two sampling strategies are proposed for their non-parametric, numerical estimation. ...
