Data sets

Vertical water vapor profiles for Boulder, Lauder, and Hilo GMD ftp://aftp.cmdl.noaa.gov/data/ozwv/WaterVapor/

Short summary

This work focuses on the balloon borne NOAA frost point hygrometer (FPH) instrument flown at three locations around the world: Boulder, Colorado, Lauder, New Zealand, and Hilo, Hawaii. The ongoing 36-year record is the longest continuous water vapor record with profiles reaching 28 km. Significant instrument updates in 2008 decreased the weight, cost, power consumption, and manufacturing time offering greater precision and ease of use.
