Understanding Radiosondes and Temperature Sounding in Atmospheric Remote Sensing

This article explores the principles of radiosonde data and temperature sounding in the context of atmospheric remote sensing, specifically focusing on water vapor absorption and its implications. It discusses the variability of atmospheric conditions and how path radiance is influenced by temperature and water vapor distribution. Utilizing resources from GOES imagery, this guide provides insights into identifying weighting functions, temperature distribution profiles, and the role of water vapor in sensing applications, crucial for meteorological analysis.

  3. If td(l) is not 0 • We will next look at case where d is relatively large due to water vapor absorption • Again, the atmosphere (path radiance) dominates • Also the source of path radiance will vary stronglywithl ,temperature, and the distribution of water vapor(since water vapor is highly variable vertically and horizontally) • Now... water vapor information Known temperature distribution and
