Short Name:

ATom: L2 In Situ Atmospheric Water Vapor from the Diode Laser Hygrometer (DLH)

This dataset provides the concentrations of water measured by the Diode Laser Hygrometer (DLH) during airborne campaigns conducted by NASA's Atmospheric Tomography (ATom) mission from 2016 - 2018. The DLH measures the water vapor (H2O(v)) in the atmosphere by wavelength modulated differential absorption spectroscopy of an isolated rovibrational line. The measurements include water vapor mixing ratio in parts-per-trillion-by-volume (pptv) and relative humidity in percent.
