Indoor Direct Comparison between High-Accuracy Pyrheliometer and Room Temperature Absolute Radiometer

Journal of Physics, Conference Series
This article proposes a practicable indoor method by directly comparing the pyrheliometer with the room temperature absolute radiometer (RTAR) to overcome the inconvenience of outdoor pyrheliometer calibration caused by the limitation of weather ...

Pyrheliometer Measurements during a Solar Eclipse in Madrid in 1914

Research Notes of the AAS
Eclipses are one of the most famous astronomical events. On 1914 August 22, a partial solar eclipse was visible from Madrid. Staff of the Astronomical Observatory of Madrid took the opportunity to conduct pyrheliometer measurements to study the decrease ...

Stratospheric aerosol forcing for CMIP7 – Part 1: optical properties for pre-industrial, historical, and scenario simulations [PDF]

Geoscientific Model Development
Stratospheric aerosols, most of which originate from explosive volcanic sulfur emissions into the stratosphere, are a key natural driver of climate variability.

Photovoltaic Power and Meteorological Datasets With Snow Detection From the Outdoor Solar Power Laboratories of the Finnish Meteorological Institute

Geoscience Data Journal, Volume 13, Issue 1, January 2026.
We describe and publish high‐resolution solar power (PV) output, ancillary, and meteorological data from three high‐latitude sites in Finland during 2015–2021. We performed quality control and daily snow cover classification on the modules based on numerical data and photographs. Snow coverage on PV modules was found to vary significantly based on site

Where numerical weather prediction meets large‐eddy simulations in a convective boundary layer during the FESSTVaL field experiment

Quarterly Journal of the Royal Meteorological Society, Volume 152, Issue 774, January 2026 Part A.
We exploit the Field Experiment on Sub‐mesoscale Spatio‐Temporal Variability in Lindenberg (FESSTVaL) to compare the performance of an NWP model at sub‐km resolutions with a traditional LES model. Focusing on clear‐sky ABL turbulence (June 14), shallow convective clouds and surface radiation (June 27), and deep convective cold pools (June 29), we find ...
