Abstract
One of the most important necessities in astronomical observatories, for operation and acquisition of good quality data, is the operation of efficient meteorological tools able to forecast in detail the atmospheric conditions in short and medium term. The European Southern Observatory (ESO) has several tools to produce such forecasts but the data gridding and temporal resolutions are low. For this reason the Astrometeorology group initiated a study to implement the WRF meteorological model over Paranal Observatory. The aim of this implementation is to find better meteorological parameterizations and forecast of the meteorological variables in high resolution. The evaluation of the model's performance will be made by comparing with meteorological data from Paranal weather station. In parallel, together with the Environmental Sciences Research Center (ESRC), a long-term study is in development to understand the evolution of the atmosphere over Paranal. This study is developed using the WRF model and the millennia simulations of the Earth's climate from the general circulation model ECHO-G.
