SUMMARY:Precipitable Water Vapour measurements and forecasting at the Obser
 vatories.
DESCRIPTION:Precipitable Water Vapour measurements and forecasting at the O
 bservatories.\nDr. Casiana Muñoz-Tuñón, Gabriel Pérez Jordán, Julio C
 astro-Almazán\n\nThe precipitable water vapour (PWV) is the main absorber
  in the Earth's\natmosphere at infrared (IR) and microwave wavelengths. In
  the last years,\nthe IAC Sky team has been providing real-time PWV data f
 rom a monitor based\non the GNSS (GPS) technique (GNSS PWV Monitors; GPM).
  Among other things,\nthe PWV values help in the scheduling of the telesco
 pes with IR\ninstrumentation. The GPM have undergone a continuous process 
 of upgrading.\nMore recently, we have undertaken the PWV forecasting. We w
 ill present in\nthe talk a brief summary of the monitors and details of Fo
 rO ("Forecasting\nthe Observatories"), the forecasting system for PWV at t
 he Observatories.\nForO is based on a mesoscale Numerical Weather Predicti
 on (NWP) model. The\nForO system has been validated and calibrated with PW
 V data from the GPM\nand will deliver accurate PWV daily predictions for O
 RM and OT on a 24, 48\nand 72 hours windows. This is a definitive improvem
 ent to optimize the\nflexible scheduling for IR observations, in particula
 r for CanaryCAM and\nEMIR at the GTC.
