This chapter explains which meteorological data we have available. Currently there are 2 meteorological models running operationally for Portugal (MM5 and WRF). The higher operational spatial resolution is 9 km but 3km are already being tested. MM5 3 day forecasts for Portugal are published on http://meteo.ist.utl.pt/. There is also available forecasts and analysis from the global model GFS which are used for initial and boundary conditions for MM5, WRF and recently WWIII. There is also a database of meteorological observations (surface and upperair).

MM5

MM5 meteorological surface forecasts are automatically being delivered to MARETEC in MOHID-HDF5 format. This section explains where are the HDF5 files. For other time periods and/or variables, or if you see that there is some file missing or has problems, please email me! (arosa@ist.utl.pt)

System Operational Configuration

MM5 is running 4 time per day (00,06,12,18 h UTC) producing 3 days forecasts with 3 spatial nested domains: D1 with 81 km resolution, D2 with 27 km and D3 with 9 km (http://meteo.ist.utl.pt/). These simulation were using GFS grib1 (1º resolution, which is ~80 km at our latitudes). Since August 2007, only 2 domains are simulated (D2 with 27 km and D3 with 9 km) because MM5 uses GFS grib2 output (0.5º resolution, which is ~40 km at our latitudes). Also, since XXX 7 days forecasts are produced four times per day.

Where are the HDF5 files?

Recent files can be found in ftp://ftp.mohid.com/ (meteoIST:mm5) where:

  1. ftp://ftp.mohid.com/mm5_6h stored in \\alexandria\public\modelos\Meteo_IST\mm5_6h
    • Each file has the 2nd 6 hours of simulation. When glued, you can have a combination of the most recent available forecast.
    • simulation 00h : files have outputs from 7:00 to 12:00
    • simulation 06h : files have outputs from 13:00 to 18:00
    • simulation 12h : files have outputs from 19:00 to 00:00
    • simulation 18h : files have outputs from 1:00 to 6:00
  2. ftp://ftp.mohid.com/mm5_7d stored in \\alexandria\public\modelos\Meteo_IST\mm5_7d
    • Simulation 00h with 7 days forecasts. This is only delivered at Friday's to run MOHID Portuguese Coast Operational Model.
  3. ftp://ftp.mohid.com/SIGEL/mm5_3d (not being stored)
    • Four daily simulations with 3 days forecasts.

MM5 forecasts

Here's the unexhaustive list of MM5 data outputs in hdf5 at Maretec data servers. There are three type of domains: D1 (~90 km), D2 (~30 km) and D3 (~10 km). However the domains changed during 2006/2007 and so there are the new D1, D2, D3 and the old D1, D2, D3.
