Remote SensingClouds are closely related to precipitation, as their type, microphysical characteristics, and dynamic properties determine the intensity, duration, and form of rainfall. While geostationary satellites offer continuous cloud-top observations, they cannot

Contemporary Accounting Research, EarlyView.ABSTRACT Whereas prior studies primarily examine how environmental shocks affect manufacturing, distribution, and supply chains, we examine a distinct and understudied channel: the effect of wildfire smoke on human capital operating from firm headquarters.

Photochemistry and Photobiology, EarlyView.Three methods for substituting on‐site ambient ultraviolet radiation measurements for personal exposure measurements were investigated. Assuming spatial persistency of measurements from high‐grade instruments delivers lowest uncertainties up to distances of 82 km.

Geophysical Research Letters, Volume 53, Issue 19, 16 October 2026.Abstract Relative sea surface temperature (SST), defined as local SST minus the tropical mean, is linked to tropical cyclone (TC) size growth, but its role in coupled size‐intensity evolution remains unclear. Using 23 years of global observations, we show that relative SST regulates very deep convection (infrared brightness temperature <208K), thereby ...

Artificial neural-network technique for precipitation nowcasting from satellite imagery [PDF]
Advances in Geosciences, 2006 The term nowcasting reflects the need of timely and accurate predictions of risky situations related to the development of severe meteorological events. In this work the objective is the very short term prediction of the rainfall field from geostationary

Instrumental Artefacts Can Reverse Apparent Lightning–Climate Trends
Geophysical Research Letters, Volume 53, Issue 19, 16 October 2026.Abstract Lightning is an Essential Climate Variable, yet long‐term detection records may be compromised by changes in detection technology. Using more than three decades of Austrian lightning observations (1992–2024), we show that instrumental artefacts can reverse the apparent sign of lightning–climate trends.

Mean Orbital Elements for Geosynchronous Orbit - I - Semi-major, eccentricity, and longitude of perigee [PDF]
Journal of Astronomy and Space Sciences, 1989 The mean orbital elements for geosynchronous satellite are developed in terms of non-singular orbital elements. The true satellite position oscillates about the position calculated from the mean elements due to short period perturbations to the satellite

Geophysical Research Letters, Volume 53, Issue 19, 16 October 2026.Abstract During a 2023 field campaign, a NASA ER‐2 research aircraft intercepted an upward jet‐like electrical discharge at 20 km altitude over an intense tropical thunderstorm. This event was analyzed using airborne multispectral optical sensors, electric field mills, X‐band radar, passive microwave, and ground‐based radio networks.
