These globes show the 20-year total column water vapor (TCWV) trend (mm/year) from AIRS Ascending/Daytime (left) and Descending/Nighttime (right) data. Statistical significance was not provided; trends should be interpreted with caution. Unlike surface air temperature, the day/night difference in the TCWV trend is small. AIRS has observed an overall increase in TCWV for South Eastern part of the United States, most of India, and Eastern China. A small drying trend is observed in the western part of the United States, including the LA Basin.
