Specialised forecasting (system ForO)

Specialised forecasting of atmospheric parameters impacting on the optical quality of astronomical observations. The predictions, generated and validated by the Sky Quality Team, are produced with the Forecasting the Observatories (ForO) system. ForO is an atmospheric prediction platform developed by the IAC based on the Weather Research and Forecasting (WRF) numerical weather prediction model.
