Abstract
New laboratory measurements and theoretical calculations of integrated line intensities for water vapour bands in the near-infrared and visible (8500- 15800 cm(-1)) are summarised. Band intensities derived from the new measure d data show a systematic 6 to 26% increase compared to calculations using t he HITRAN-96 database. The recent corrections to the HITRAN database [Giver et al., J. Quant. Spectrosc. Radiat. Transfer, 66, 101-105, 2000] do not r emove these discrepancies and the differences change to 6 to 38 %. The new data is expected to substantially increase the calculated absorption of sol ar energy due to water vapour in climate models based on the HITRAN databas e.
