GOES Satellite Reveals Atmospheric Moisture Layers
Recent analysis using GOES-East water vapor imagery has provided insights into atmospheric moisture distribution across the United States. On October 30, 2026, forecasters observed significant differences in moisture levels across various atmospheric layers. Data from Springfield, MO, revealed widespread upper-level moisture, while mid-level layers remained notably dry. This discrepancy was confirmed using balloon soundings and satellite-derived weighting functions, which measure radiation contributions from different atmospheric layers. The imagery highlighted colder brightness temperatures in upper-level channels (-40°C/-40°F) compared to warmer temperatures in lower-level channels (-20°C/-4°F). Similar observations were made in Pittsburgh, PA, where drier conditions allowed deeper atmospheric layers to be sensed. These findings underscore the importance of understanding satellite imagery's sensitivity to varying atmospheric conditions.
