ADC Performance in Microwave Radiometer

Journal of Radio Electronics, 2023
The configuration of a microwave switched radiometer is considered. The grounds that guide developers in determining the requirements for the ADC sampling rate are analyzed. It is shown that the ADC rate can be significantly reduced if an additional analog integrator is installed at the ADC input. Statistical modeling of such a circuit has been carried

Dominant Role of Soil Moisture Regulating Vegetation Water Content During Flash Drought Evolution

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract Increasing flash drought exposure raises global concerns regarding terrestrial ecosystem responses. We investigate the effect of concurrent and past rootzone soil moisture (SM) and vapor pressure deficit (VPD) on vegetation optical depth (VOD), a satellite‐based proxy of vegetation‐water content, during flash drought evolution.

An integrated approach toward the incorporation of clouds in the temperature retrievals from microwave measurements [PDF]

Atmospheric Measurement Techniques, 2014
In this paper, we address the characterization of clouds and its inclusion in microwave retrievals in order to study its effect on tropospheric temperature profiles measured by TEMPERA radiometer.

Process‐Oriented Calibration of a Turbulence Scheme in the DOE's Global Storm‐Resolving Model Using Machine Learning

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract A process‐oriented calibration framework is developed for the Simplified Higher‐Order Closure (SHOC) turbulence scheme in DOE's Simple Cloud Resolving E3SM Atmospheric Model (SCREAM). This framework leverages machine learning surrogates and observational constraints to efficiently calibrate SHOC adjustable parameters across two convective ...

Long‐Term Observations Reveal Non‐Negligible Temperature Contributions to Moist Static Energy During the MJO Transition From Suppressed to Active Phases

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract The evolution of moist static energy (MSE) is widely used to understand the organization and propagation of the Madden‐Julian Oscillation (MJO). Past studies, largely based on reanalysis or short‐term observations, have highlighted humidity as the dominant driver of MJO evolution.

Anomalous Opaque Clouds Revealed by Collocated MODIS and CALIOP Retrievals

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract This paper examines discrepancies between cloud optical thickness (COT) retrievals from the Moderate Resolution Imaging Spectroradiometer (MODIS) cloud product, and cloud opacity measurements from the Cloud‐Aerosol Lidar with Orthogonal Polarization (CALIOP) lidar.
