MoDLS combines in-situ surface measurements with ground-based remote sensing measurements to capture complete boundary layer turbulence and flux measurements. A retractable infrared radiometer is mounted to the outside of the truck. The infrared radiometer is directed at the ground to provide surface skin temperature which is useful for documenting surface flux and lapse rates. Downwelling solar radiation is also measured via an Eppley Labs Solar Pyranometer. Mounted to the telescoping mast, a RM Young 81000 3D sonic anemometer and a thermistor temperature probe are measured at 8 meters above ground level (AGL), and a Gill GMX 600 all-in-one weather sensor (temperature, RH, pressure, 2D wind, and precipitation rate) is mounted at 4 meters AGL. The sonic anemometer can provide U, V, & W winds and sonic temperature at 4-32 Hz. All other sensors measure at 1 Hz.
