= Daten = Die Daten auf dem aktuellen Wolken Layer werden aus den Daten von drei verschiedenen Modellen des kanadischen Wetterdienst abgeleitet.


 * 1) Global Deterministic Prediction System (GDPRS). Das GDPS oder Global Model ist das am niedrigsten auflösende Modell. Es hat eine eine Rasterauflösung von 33 km und die den ganzen Globus abdeckt. Die niedrige Auflösung macht es möglich Voraussagen für 72 Stunden und darüber hinaus zu machen. In GeoMet forecast data from the Global model is offered out to 72 hours.  Data is offered at the surface or ETA levels and also at constant pressure levels. Forecast data is presented in increments of 3 hours.


 * 1) Regional Deterministic Prediction System (RDPS) The RDPS or Regional Model is a higher resolution model offered. It has a grid resolution of 15 km over North America and adjacent waters with a lower resolution grid beyond this core. Due to the higher resolution, forecasts in the Regional Model are generated out to 48 hours only. Forecast data is presented in increments of 3 hours.


 * 1) Global Environmental Multiscale - Local Area Model (GEM-LAM). The GEM LAM model is the highest resolution meteorological model offered by Environment Canada. It has a grid resolution of 2.5km. Its high resolution means that if can only be offered on a regional scale due to the amount of computer resources required to run it. The GEM LAM has 4 regional domains:
 * GEM LAM West (BC and Alberta)
 * GEM LAM East (Ontario and Quebec)
 * GEM LAM Maritime (Maritime Provinces)
 * GEM LAM Arctic (Baffin Island).
