PyDDA: A Pythonic Direct Data Assimilation Framework for Wind Retrievals

open access: yesJournal of Open Research Software, 2020
This software assimilates data from an arbitrary number of weather radars together with other spatial wind fields (eg numerical weather forecasting model data) in order to retrieve high resolution three dimensional wind fields. PyDDA uses NumPy and SciPy’

Observation Impact of Moored Buoys in the Eastern Tropical Indian Ocean During Boreal Winter Using Ensemble‐Based Forecast Sensitivity to Observations

open access: yesAtmospheric Science Letters, Volume 27, Issue 6, June 2026.
Using 17 years of ensemble‐based forecast sensitivity to observations (EFSO), this study shows that marine meteorological observations in the eastern tropical Indian Ocean have significantly larger impacts during boreal winter than summer, despite similar observation frequencies.

Cross-Validation of Observations between the GPM Dual-Frequency Precipitation Radar and Ground Based Dual-Polarization Radars

open access: yesRemote Sensing, 2018
The Global Precipitation Measurement (GPM) mission Core Observatory is equipped with a dual-frequency precipitation radar (DPR) with capability of measuring precipitation simultaneously at frequencies of 13.6 GHz (Ku-band) and 35.5 GHz (Ka-band).

Beyond birds: rethinking bird‐centered pathogen models in light of insect migration

open access: yesEcography, Volume 2026, Issue 6, June 2026.
Migration redistributes biomass, nutrients, and pathogens across ecosystems. For decades, migratory birds have been treated as the default long‐distance pathogen vectors, shaping both conceptual frameworks and empirical models of disease ecology.

The effect of watershed scale on HEC-HMS calibrated parameters: a case study in the Clear Creek watershed in Iowa, US [PDF]

open access: yesHydrology and Earth System Sciences, 2013
In this paper, we use the Hydrologic Modeling System (HEC-HMS) to simulate two flood events to investigate the effect of watershed subdivision in terms of performance, the calibrated parameter values, the description of hydrologic processes, and the ...

Influence of Surface Conditions on the 04 July 2025 Extreme Storms in Central Texas

open access: yesGeophysical Research Letters, Volume 53, Issue 10, 28 May 2026.
Abstract The impactful 04 July 2025 Central Texas extreme rainfall event is examined to understand how surface conditions influence storm development. Utilizing convection‐permitting model simulations, we evaluate the sensitivity of this event to Gulf of Mexico sea surface temperature anomalies (SSTAs) and antecedent soil moisture distributions.

Mass mortality of saguaros (Carnegiea gigantea) from windthrow: A rare, demographic disturbance in a desert ecosystem

open access: yesEcosphere, Volume 17, Issue 5, May 2026.
Abstract Windthrow is a significant disturbance in many forests globally during which strong winds damage trees or other large flora, yet its role in arid ecosystems remains largely understudied. The saguaro cactus (Carnegiea gigantea), a keystone species of the Sonoran Desert, is a long‐lived, massive succulent whose demography is primarily thought to
