Retrieval of meteo data from ecmwf

Retrieval/Download procedure

1 telnet ecaccess.ecmwf.int

1.1 login: ugq
1.2 password: given by the identity token after introducing the numerical key
1.3 enter
1.4 enter

2 change the script "campi_2d-3d_analisi"

DATEINI='2007052200'
DATEFIN='2007052400'
AREA=60.0/-35.0/5.0/50.0 # N/W/S/E
GRID=0.5/0.5
LEVELS=91 (risoluzione e livelli del modello ECMWF cambiano in funzione dell'anno: verificare dalla tabella sotto)

3 run the script:
```
llsubmit campi_2d-3d_analisi
```
4 go to scratch/dati
```
cd $scratch/dati
```
5 download data
```
scp 2D* 3D* phig_* utente@macchina
```
Remark: the file psig_* contains the orography and is generated using the first day as a label. If generated multiple times (e.g., by executing the retrieval procedure in more than one step, for the same domain/resolution, different files would be the equal.

Anyway, generally the name of the file should be associated to the first day of run!
