On the Applicability of Ground-Based Microwave Radiometers for Urban Boundary Layer Research [PDF]

open access: yesSensors
Significant knowledge gaps exist in our understanding of urban boundary layer processes, particularly the hygrothermal state. The earth system community has successfully used microwave radiometers for several decades.

Performance of Forecasts of Hurricanes with and without Upper-Level Troughs over the Mid-Latitudes

open access: yesAtmosphere, 2020
We investigated the accuracy of operational medium-range ensemble forecasts for 29 Atlantic hurricanes between 2007 and 2019. Upper-level troughs with strong wind promoted northward movement of hurricanes over the mid-latitudes. For hurricanes with upper-

Tropospheric Gravity Waves Increase the Likelihood of Double Tropopauses

open access: yesGeophysical Research Letters, 2023
The tropopause region is crucial for the stratosphere‐troposphere exchange (STE) and acts as an indicator of climate change. Double tropopauses (DTs) act to increase the STE process but their driving mechanisms remain an open question.

Precipitable Water Vapour Retrieval from GPS Precise Point Positioning and NCEP CFSv2 Dataset during Typhoon Events

open access: yesSensors, 2018
Radiosonde is extensively used for understanding meteorological parameters in the vertical direction. Four typhoon events, including three landfalls (MERANTI, NEPARTAK, and MEGI) and one non-landfall (MALAKAS), were chosen in analysing the precipitable ...

An Empirical Grid Model for Precipitable Water Vapor

open access: yesRemote Sensing, 2022
Atmospheric precipitable water vapor (PWV) is a key variable for weather forecast and climate research. Various techniques (e.g., radiosondes, global navigation satellite system, satellite remote sensing and reanalysis products by data assimilation) can ...

Comprehensive Validation and Calibration of MODIS PWV over Mainland China

open access: yesAtmosphere, 2022
Although ground-based precipitable water vapor (PWV) can be obtained with a high temporal resolution and spatial resolution of tens of kilometers in an urban area using Global Navigation Satellite System (GNSS) observation, it remains fairly sparse in ...
