Journal ArticleDOI
Decreases in stratospheric water vapor after 2001: Links to changes in the tropical tropopause and the Brewer-Dobson circulation
TL;DR: In this paper, the authors show that the tropical tropopause has been anomalously cold during this period, and the observed water vapor changes (approximately −0.4 ppmv) are consistent with the temperature decreases.
Journal ArticleDOI
Absolute accuracy of water vapor measurements from six operational radiosonde types launched during AWEX-G and implications for AIRS validation
Larry M. Miloshevich,Holger Vömel,David N. Whiteman,Barry M. Lesht,F. J. Schmidlin,Felicita Russo +5 more
TL;DR: In this paper, the mean accuracy and variability of the radiosonde water vapor measurements relative to simultaneous measurements from the University of Colorado (CU) Cryogenic Frostpoint Hygrometer (CFH), a reference-quality standard of known absolute accuracy, were determined.
Journal ArticleDOI
Accuracy assessment and correction of Vaisala RS92 radiosonde water vapor measurements
TL;DR: In this article, the mean bias error of Vaisala RS92 radiosondes is characterized as a function of its known dependences on height, relative humidity, and time of day (or solar altitude angle).
Journal ArticleDOI
Radiation Dry Bias of the Vaisala RS92 Humidity Sensor
Holger Vömel,Henry B. Selkirk,Larry M. Miloshevich,J. Valverde-Canossa,J. Valdés,Esko Kyrö,Rigel Kivi,W. Stolz,G. S. Peng,Jorge Andres Diaz +9 more
TL;DR: In this article, a comparison of simultaneous humidity measurements by the Vaisala RS92 radiosonde and by the Cryogenic Frostpoint Hygrometer (CFH) launched at Alajuela, Costa Rica, during July 2005 reveals a large solar radiation dry bias of the RS92 humidity sensor and a minor temperaturedependent calibration error.

TL;DR: The validation of version 2.2 (v2.2) H2O measurements from the Earth Observing System (EOS) Microwave Limb Sounder (Aura MLS) on the Aura satellite is presented in this article.
