Increasing Alaskan river discharge during the cold season is driven by recent warming
Arctic hydrology is experiencing rapid changes including earlier snow melt, permafrost degradation, increasing active layer depth, and reduced river ice, all of which are...- publication PDF

A new MHD-assisted stokes inversion technique
We present a new method of Stokes inversion of spectropolarimetric data and evaluate it by taking the example of a SUNRISE/IMaX observation. An archive of synthetic Stokes...- publication PDF

Stratified flow past a sphere at moderate Reynolds numbers
A numerical study of stably stratified flows past spheres at Reynolds numbers Re = 200 and Re = 300 is reported. In these flow regimes, a neutrally stratified laminar flow...- publication PDF

Global gridded crop model evaluation: benchmarking, skills, deficiencies and...
Crop models are increasingly used to simulate crop yields at the global scale, but so far there is no general framework on how to assess model performance. Here we evaluate the...- publication PDF

A formula for the maximum vertical velocity in supercell updrafts
In supercell environments, previous authors have shown strong connections between the vertical wind shear magnitude, updraft width, and entrainment. Based on these results, it...- publication PDF

Commentary on “O variability in the troposphere...
Evaluation and attribution of variability and trends in tropospheric ozone requires consideration not only of the spatial distribution of ozone precursor emissions and their...- publication PDF

Climate response and radiative forcing from mineral aerosols during the last...
Mineral aerosol impacts on climate through radiative forcing by natural dust sources are examined in the current, last glacial maximum, pre-industrial and doubled-carbon dioxide...- publication PDF

Variability in upwelling across the tropical tropopause and correlations...
Temporal variability of the upwelling near the tropical tropopause on daily to annual timescales is investigated using three different estimates computed from the ERA-Interim...- publication PDF
