Introduction to the Special Collection: Analyzing Big Data for Understanding Climate Variability, Natural Phenomena, and Rapid Environmental Changes

Earth and Space Science, Volume 12, Issue 10, October 2025.
Abstract Climate variability affects multiple processes on Earth, with significant system effects driving hydrometeorological, glaciological, atmospheric, and geophysical variability. Research into these fields is driven by acquisition and processing of voluminous amount of data at multiple spatial and temporal scales. Intersection of data and tools to

The Need for Better Monitoring of Climate Change in the Middle and Upper Atmosphere

AGU Advances, Volume 6, Issue 2, April 2025.
Abstract Anthropogenic greenhouse gas emissions significantly impact the middle and upper atmosphere. They cause cooling and thermal shrinking and affect the atmospheric structure. Atmospheric contraction results in changes in key atmospheric features, such as the stratopause height or the peak ionospheric electron density, and also results in reduced ...

Spectral Extension of the CPF‐Measured Earth‐Reflected Solar Radiances for CPF‐CERES Intercalibration

Journal of Geophysical Research: Atmospheres, Volume 130, Issue 4, 28 February 2025.
Abstract The Climate Absolute Radiance and Refractivity Observatory (CLARREO) Pathfinder (CPF) mission is set to launch an SI‐traceable reflective solar (RS) spectrometer aboard the International Space Station to measure Earth‐reflected solar radiation with a radiometric uncertainty of 0.3%–0.6% (k = 1).
