The self-contained mobile WindLab designed by Atmospheric Research & Technology includes a trailer-mounted Model VT-1 sodar for remote measurements of the wind profile. The unit comes complete with an on-board solar power system for independent operation at virtually any location. The Model VT-1 sodar is provided assembled and mounted within a fully-enclosed customized cargo trailer ready to be towed to your first monitoring site.  The unit can be deployed in minutes and just as quickly prepared for relocation. The sodar and other equipment are protected and secure within the durable trailer. The trailer also improves sodar performance and affords a sheltered and convenient workspace for the operator. Side-lobe energy captured by the foam-lined trailer interior reduces echo interference due to ground clutter and minimizes nuisance noise from sodar operation.
