MOHAVE 2009 Data Workshop: Analysis of Radiosondes and Frostpoint Hygrometers

This workshop focuses on the analysis of data collected during the MOHAVE 2009 mission, comparing results from RS92 radiosondes and frostpoint hygrometers. The workshop covers various parameters such as pressure, temperature, altitude, relative humidity, and H2O volume mixing ratio. Key insights include pressure differences, temperature variations, altitude discrepancies, and RH inconsistencies between different instruments. The summary statistics highlight the precision and biases in the collected data. Join us from October 18 to 21, 2010, for an in-depth exploration of atmospheric measurements.
