- Daily Specific Humidity
- Abstract
- <p>Specific humidity is a measure of the amount of moisture in the air per unit weight of dry air. Shifting patterns of specific humidity, as projected by the Met Office Hadley Centre climate models, can influence indoor air quality conditions, with consequential impacts to occupant health. To help illustrate these patterns, the average annual specific humidity (g H<sub>2</sub>O / kg dry air) is mapped for the average year in the time period for the 50th and 95th percentile models out of the 12-model suite. Time periods are baseline (1980-2000), 2030 (2021-2040), and 2070 (2061-2080). County-level results represent an area-weighted-average of the results for each climate data grid within the county.</p> <p>Additional information is available here: <a
