On this site we provide free hourly weather forecasts over a territory of Northern Italy and Switzerland of 200x200 km2, with 250 m of spatial resolution of the wind field at 10 m above the ground.
The forecasts here provided are up to 48 hours and are generated with the GFS - WRF 4.1 - CALWRF 2.0.2 - CALMET 6.5 modeling system running automatically on our computing infrastructure dedicated to the production of the meteorological datasets that we market and use for our services consultancy in the field of air pollution, olfactory pollution and meteorology.
Our high-resolution forecast system can be positioned anywhere on the globe and can be queried via an API to extract forecasts at single points on the ground and aloft, along routes, vertical profiles or three-dimensional trajectories, and on planar sections.
The WRF model is initialized with GFS data at 0.25 ° (18 UTC cycle for the data here provided) and is running on three nested domains with resolutions of 27 km, 9 km and 3 km, respectively.
The 3km forecast output data from the WRF model are used in cascade to initialize the CALMET diagnostic meteorological model with 250 m resolution. This allows us to detail the circulation even within the valleys, reconstructing the slope winds.
The CALMET output files, available as 50x50 km2 tiles, can be used with the model for simulating the dispersion of pollutants in the atmosphere CALPUFF or with our Lagrangian particle model LAPMOD.
The WRF data is also processed with the US-EPA's MMIF processor to prepare and execute the AERMET code and generate weather input for the US-EPA's AERMOD model. From the high-resolution point data visualization interface it is possible to download the compressed and password-protected archive with the data produced by AERMET for the point of the WRF domain at 3 km, closest to the selection.
The forecast data available here are provided without any guarantee of correctness and appropriateness for their possible use. The user is solely responsible for these assessments and by using them he relieves Enviroware srl of any responsibility. You are requested to cite this web page as the source of the data.
To use the downloaded datasets you need a password which you can request by writing to info@enviroware.com, specifying the purpose of the application.
