Spatial Variability of L-Band Brightness Temperature during Freeze/Thaw Events over a Prairie Environment

Remote Sensing, 2017
Passive microwave measurements from space are known to be sensitive to the freeze/thaw (F/T) state of the land surface. These measurements are at a coarse spatial resolution (~15–50 km) and the spatial variability of the microwave emissions within a ...

Enhanced Full Spectral Temperature‐Dependent Refractive Index of Liquid Water From Supercooled to Ambient Conditions

Geophysical Research Letters, Volume 53, Issue 6, 28 March 2026.
Abstract A new compilation of the complex refractive index of liquid water is presented, spanning temperatures from 240 $240$ (near homogeneous freezing) to 300 $300$ K and wavelengths from 0.034 $0.034$ μm to 10 m. The real part of the refractive index is derived using the Kramers–Kronig relation, where the imaginary part is constrained by ...

Observation of Mountain Waves and Secondary Gravity Waves in the Mesosphere Lower Thermosphere Above Patagonia

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 6, 28 March 2026.
Abstract We find observational evidence for mountain waves (MWs) and secondary gravity waves (2GWs) in the OH*(3‐1) layer above Tierra del Fuego, Argentina. On the night of 21–22 May 2018, the Advanced Mesospheric Temperature Mapper (AMTM) obtained temperatures at ∼84 ${\sim} 84$ km.

Ground-based Multichannel Microwave Radiometer Antenna Pattern Measurement using Solar Observations [PDF]

, 2020
Abstract. Ground-based multichannel microwave radiometers (MWRs) can provide continuous temperature and humidity profiles of the troposphere. MWR antenna pattern measurements are important for reliable and accurate antenna temperature measurement and are usually carried out in a microwave anechoic chamber.

Surface Observations From Atmospheric Radiation Measurement Sites Constrain the Anthropogenic Contribution to Cloud Droplet Number

Geophysical Research Letters, Volume 53, Issue 5, 16 March 2026.
Abstract Uncertainty in anthropogenic forcing driven by aerosol‐cloud interactions (aci) limits our ability to infer the sensitivity of the Earth system to forcing from historical records. The driver of aci is the change in cloud droplet number concentration (Nd) due to changes in aerosol serving as cloud condensation nuclei (CCN).

A Novel Approach to Enhancing Spatial Resolution in Submillimeter‐Wave Ice Cloud Parameter Retrieval

Atmospheric Science Letters, Volume 27, Issue 3, March 2026.
This study summarizes research that we reduce the impact of ice cloud horizontal heterogeneity in sensor footprint on retrieval. Specifically, we have mitigated the impact of the ice cloud plane parallelism assumption by improving the retrieval resolution.

Evaluation and Improvement of the Quality of Ground-Based Microwave Radiometer Clear-Sky Data

Atmosphere, 2021
To assess the quality of the retrieved products from ground-based microwave radiometers, the “clear-sky” Level-2 data (LV2) products (profiles of atmospheric temperature and humidity) filtered through a radiometer in Beijing during the 24 months from ...
