Web Interface

 

This system currently generates two final products:

1. PWV forecasts time series: 2 independent time series, for ORM and OT.
2. PWV forecast 2D charts: for the desired domains (d01 (27km), d02 (9km), d03 (3km)), centered at each observatory (ORM and OT).

While product 1 (PWV time series) shows the predicted PWV above the specific observatory, product 2 (PWV color plots) provides a 2D view of the PWV structure above the observatory height at synoptic scale for 3 different model domains at horizontal resolutions of 27, 9 and 3 kilometers, as shown in the following examples:


The WRF model is centered above each observatory coordinales, which are:
For Observatorio del Roque de los Muchachos (ORM): 28.76° Latitude -17.88° Longitude
For Observatorio del Teide (OT): 28.30° Latitude -16.51° Longitude



These two products are further described in specific tutorials accessible through the icon in the text above each product.

The raw output of the WRF model is automatically adjusted following the calibration described in Pérez-Jordán et al (2015) and Castro-Almazán et al (2016) for a model horizontal resolution of 3km, using high resolution radiosoundings. The PWV time series include the Total Forecast Error as described in full detail in Pérez-Jordán et al (2018). The detailed configuration of the WRF model implemented in ForO can also be found in this later publication.

Besides display of forecasted PWV above the observatories, the web interface allows the user to check the state of the current WRF run (if the model is running in that moment) or know the next scheduled time for WRF model run. Finally, a Download sections allows the user to get PWV historical data from the system in ASCII format up to 6 months (different options available in the drop-down menu):


The ForO system architecture allows to add new meteorological parameters for forecasting in future phases, without impacting system arquitecture.
