Land surface Interactions with the Atmosphere over the Iberian Semi-arid Environment


The LIAISE database is hosted by AERIS under the HyMeX data policy. Data is being continuously updated as it is processed: please see the site for a listing of data.

  • Data can be uploaded (including metadata) and downloaded from the LIAISE AERIS DB.
  • A document describing the database usage procedures is available.
  • If you have never registered or accessed the data and wish to, please first register on the AERIS site, then send a mail to aaron.boone@meteo.fr to be granted download access.

LIAISE Data not on the AERIS database:

Some datasets taken during the LIAISE field campaign are located on other servers but can be accessed. Please see the links below for further information or data access.

  • The Scanning L-band Active/Passive (SLAP) data from the airborne simulator of NASA's Soil Moisture Active/Passive (SMAP) satellite data aquired during the SOP can be accessed on a NASA data server.
  • Certain data (surface flux data for the Boldu irrigated corn, the irrigated vinyard at the Verdu site, SIF at La Cendrosa, GLORI soil mositure etc...) can be found on the CESBIO Système d'Information Environnemental (SIE) server.
