Predicting Convective Downdrafts From Updrafts and Environmental Conditions in a Global Storm Resolving Simulation
(
- Journal of Advances in Modeling Earth Systems
, 2023-03-02)
One important component of precipitating convection is the formation of convective downdrafts. They can terminate the initial updraft, affect the mean properties of the boundary layer, and cause strong winds at the surface. ...
The influence of Antarctic ice loss on polar motion: an assessment based on GRACE and multi-mission satellite altimetry
(
- Earth, Planets and Space
, 2021-04-23)
Increasing ice loss of the Antarctic Ice Sheet (AIS) due to global climate change affects the orientation of the Earth’s spin axis with respect to an Earth-fixed reference system (polar motion). Here the contribution of ...
Baseline Vector Repeatability at the Sub‐Millimeter Level Enabled by Radio Interferometer Phase Delays of Intra‐Site Baselines
(
- Journal of Geophysical Research: Solid Earth
, 2023-03-17)
We report the results of position ties for short baselines at eight geodetic sites based on phase delays that are extracted from global geodetic very‐long‐baseline interferometry (VLBI) observations rather than dedicated ...
Regional Impact of Snow‐Darkening on Snow Pack and the Atmosphere During a Severe Saharan Dust Deposition Event in Eurasia

Intercomparison of different state-of-the-art formulations of the mass density of humid air
(
- Bulletin of Atmospheric Science and Technology
, 2021-12-17)
The differences between one classical and three state-of-the-art formulations of the mass density of humid air were quantified. Here, we present both the calculi for direct determination of the humid-air mass density ...
Optical clock technologies for global navigation satellite systems
(
- GPS Solutions
, 2021-04-05)
Future generations of global navigation satellite systems (GNSSs) can benefit from optical technologies. Especially optical clocks could back-up or replace the currently used microwave clocks, having the potential to improve ...
A new method to estimate GPS satellite and receiver differential code biases using a network of LEO satellites
(
- GPS Solutions
, 2021-03-09)
The differential code biases (DCBs) of the global positioning system (GPS) receiver onboard low-Earth orbit (LEO) satellites are commonly estimated by a local spherical symmetry assumption together with the known GPS ...

3D Reconstruction of Bridges from Airborne Laser Scanning Data and Cadastral Footprints
(
- Journal of Geovisualization and Spatial Analysis
, 2021-04-12)
The given paper describes a method for automatic 3D reconstruction of bridges from cadastral footprints and airborne laser scanning point clouds. The reconstructed bridges are used to enrich 3D city models. Unlike roofs, ...
