What simulations available ?

There are three simulations from IPSL, available for the entire CIRCE community. In the following, they are referred to as "ipsl1", "ipsl2" and "ipsl3" respectively. All three cover the period from 1951 to 2050 (100 years) and correspond to the IPCC-A1B scenario for the period 2001 to 2050. They cover the mediterranean basin with a spatial resolution of about 35 km.

Where to download the data ?

Data in NetCDF format can be retrieved from our DODS server "http://dodsp.idris.fr/rces111/yangzi"

In a near future, a mirror ftp server in IPSL may be available

You may know already that GNU "wget" is a non-interactive network downloader which is helpful to manage a large number of files to download.

How to do if I have specific demands ?

If you don't have the capability to download all data or to save them on your local system, you may ask Laurent Li to do some specific diagnostics for you.
