Despite the implication of aerosols for the radiation budget, there are persistent differences in data for the aerosol optical depth (τ) for 1998–2019. This study…
Model estimates of expected photovoltaic (PV) power production rely on accurate irradiance data. Reanalysis and satellite products freely provide irradiance data with a high temporal and spatial resolution including…
Based on the numerical weather prediction model COSMO of Germany’s national meteorological service (Deutscher Wetterdienst, DWD), regional reanalysis datasets have been developed with grid spacing…
Many applications require wind gust estimates at very different atmospheric height levels. For example, the renewable energy sector is interested in wind and gust predictions…
The increasing use of wind and solar power requires interventions to balance the associated variability in energy production. One option to reduce the costly interventions…
RESEARCHERS SHOW HOW CLIMATE-NEUTRAL ENERGY SUPPLY IS POSSIBLE EVEN UNDER EXTREME WEATHER CONDITIONS
Scientists at the University of Cologne are investigating how an energy system with a high share of renewables can work even in extreme weather situations.…
We show how changes in the global distribution of anthropogenic aerosols favor different spatial patterns in the North Atlantic sea-surface temperature (NASST). The NASSTs largely…
Spring 2020 broke sunshine duration records across Western Europe. The Netherlands recorded the highest surface irradiance since 1928, exceeding the previous extreme of 2011 by…
The pandemic in 2020 caused an abrupt change in the emission of anthropogenic aerosols and their precursors. We estimate the associated change in the aerosol…
Researchers from the University of Cologne were the PIs in charge of the FESSTVaL campaign on the first 2 weeks of August (weeks 12 and…
Future regional reanalysis will move towards finer grid spacing with a better representation of land surface heterogeneity thus especially enhancing the representation of the boundary layer…
With regard to the application of reanalysis data, a comprehensive assessment of the quality of the reanalysis is needed. Therefore, we are continuously developing an…
We are using reanalyses for renewable energy assessments in Germany and Europe. This includes climatological assessments of potential challenges in the production of renewable power,…
Post-processing in weather and climate is aimed at enhancing the output of meterological models by applying a statistical modeling framework using the simulated estimates…
In 2020 and 2021 this HErZ branch is actively participating in the measurement campaigns FESST@home and FESSTVaL (Field Experiment on Submesoscale Spatio-Temporal Variability in Lindenberg,…
