Field crew collecting validation information for remote sensing products.

Field crew measuring cover of Lehmann Lovegrass (Eragrostis lehmanniana) and Boer Lovegrass (E. curvula var. conferta = E. chloromelas) in a desert grassland of southern Arizona. 

Instruments continue to collect vital data during workplace closures. Here staff perform maintenance on an eddy flux tower located within a phragmites wetland at the Cape Cod National Seashore. The instruments on this tower measure methane and CO2 fluxes related to plant and soil processes day in and day out for the entire year.
