‎Where are the HDF5 files?

New page

This chapter explains which meteorological data we have available.
Currently there are 2 meteorological models running operationally for Portugal ([http://www.mmm.ucar.edu/mm5/ MM5] and [http://www.wrf-model.org/ 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/ http://meteo.ist.utl.pt/].
There is also available forecasts and analysis from the global model [http://en.wikipedia.org/wiki/Global_Forecast_System GFS] which are used for initial and boundary conditions for MM5, WRF and recently [http://www.maretec.mohid.com/ww3/ 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===
[http://www.mmm.ucar.edu/mm5/ 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/ http://meteo.ist.utl.pt/]). These simulation were using [http://en.wikipedia.org/wiki/Global_Forecast_System 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:

#'''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
#'''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.
#'''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.
