The STARTWAVE database

The STARTWAVE database makes available ground based measurements of water vapour and liquid water from various instrument networks in Switzerland.

STARTWAVE data can be used for scientific purposes only. To become a user you must first accept the conditions for using the database and register.

You can download small amounts of data on a trial basis by giving the user name startwave_demo and leaving the password line blank when you are asked for your user name and password. Your query will be restricted to 100 lines.
