  1. value-added product (VAP) Physical models using ARM instrument data as inputs used to fulfill some of the unmet measurement needs of the ARM Program and to improve the quality of…
  2. Vapor Pressure The partial pressure of water vapor in an air-water system.
  3. varve annual layer of sediment deposited in an ocean or lake.
  4. Vehicle miles traveled (VMT) One vehicle traveling the distance of one mile. Thus, total vehicle miles is the total mileage traveled by all vehicles.
  5. Vertical Velocity The component of velocity (motion) in the vertical. The evaluation of areas of upward vertical velocity is key to forecasting areas of active weather.
  6. Virga Streaks or wisps of precipitation falling from a cloud but evaporating before reaching the ground.
  7. Virtual Temperature The virtual temperature is the temperature a parcel which contains no moisture would have to equal the density of a parcel at a specific temperature and…

  11. Volatile organic compounds (VOCs) Organic compounds that evaporate readily into the atmosphere at normal temperatures.
  12. Vortex A revolving mass of water (whirlpool) in which the streamlines are concentric circles and in which the total head is the same.
  13. Vorticity A measure of the rotation of air in a horizontal plane. Positive (counter-clockwise or cyclonic) vorticity can be correlated with surface low development…
  14. Vostok site in Antarctica (78°S, 106°E) where a 400,000 year long ice core was collected.
