Located in the lower foothills of the Sierra Nevada Mountains on privately owned land, the Vaira Ranch site is classified as a grassland dominated by C3 annual grasses. Managed by local rancher, Fran Vaira, brush has been periodically removed for cattle grazing. Species include a variety of grasses and herbs, including purple false brome, smooth cat's ear, and rose clover. Growing season is confined to the wet season only, typically from October to early May.

Met data collected at Vaira
Soil moisture data from the Vaira Moisture Point probes.
Half hour averages of the 10Hz flux data.
Soil CO2 data collected from nine Vaisala CO2 probes in three profiles.
Originally the soil sensors (TC, sm, SHF) were on a CR10x. 4-way radiometer and diffuse PAR were added later. All sensors were moved to CR23x on 2004-07-25
