Water Vapor #3: Updated NIR Results

Apr 12, 2005 – 8:52 PM

Since 2000, there have been a number of very important new studies, increasing the estimated NIR absorption parameters of water vapor, stimulated by the discovery of the HITRAN-96 clerical errors, but amounting to significant increases over and above those errors. The increases seem to account for much missing atmospheric absorption. Again, the issue here is […]

Water Vapor #2: HITRAN 96 Errors

Apr 11, 2005 – 11:47 AM

By 1999, systematic errors in the HITRAN-96 database for NIR water vapor absorption (which oppose water vapor feedback!) had been identified and widely reported by the most eminent authorities. For example, Systematic errors have been found and corrected in the HITRAN (High Resolution Transmission Molecular Absorption Database) water vapor line absorption intensities in the visible […]

Water Vapor #1

Apr 11, 2005 – 6:43 AM

I notice that some posters have been discussing water vapor feedbacks and thought that I’d chip in a little. One aspect of water vapor’s role in the climate system that I find intriguing is absorption of near infrared (NIR) and visible solar radiation by water vapor. This is a topic of very active research by […]
