Patterns and trends of ozone and carbon monoxide at Ushuaia (Argentina) observatory
(Elsevier, 2021-06)Resumen
The behavior patterns for surface ozone (O3) and carbon monoxide (CO) were investigated with the hourly mixing ratios registered for nine years (2010 to 2018) at the GAW-WMO (Global Atmospheric Watch – World Meteorological ... -
Previsão estatística da precipitação de verão no centro-oeste da Argentina
(Universidade Federal de Santa María, 2015-01)Resumen
This paper attempts to understand the rainfall interannual variability in order to predict seasonal precipitation using a linear regression model. This work analyze summer precipitation (December, January and February) in ... -
Reactive bromine in the low troposphere of Antarctica: estimations at two research sites
(Atmospheric Chemistry and Physics, 2018)Resumen
For decades, reactive halogen species (RHSs) have been the subject of detailed scientific research due to their influence on the oxidizing capacity of the atmosphere and on the climate. From the RHSs, those containing ... -
Sensibilidad de un sistema de asimilación de datos por ensambles a diferentes configuraciones, implementado en el Sur de Sudamérica
(Centro Argentino de Meteorólogos, 2019-07)Resumen
Uno de los mayores desafíos en la predicción numérica del tiempo es el de reducir la incertidumbre de las condiciones iniciales. Con el fin de abordar esta problemática, variados esfuerzos se están llevando a cabo en el ... -
Sensitivity of WRF short-term forecasts to different soil moisture initializations from the GLDAS database over South America in March 2009
(Elsevier, 2016-01-01)Resumen
In Numerical Weather Prediction models it is essential to properly describe both the atmosphere and the surface initial conditions. With respect to the last, a major issue is the difficulty to attain a correct representation ... -
The false alarm/surprise trade‑of in weather warnings systems: an expected utility theory perspective
(Springer, 2022-05)Resumen
Early warning systems for weather events are becoming widespread as technological capacities develop. For warnings to be efective, they must allow enough lead time to deploy protective measures yet the earlier a warning ... -
The UV Index color palette revisited
(Elsevier, 2023-04-27)Resumen
The UV Index (UVI), standardized by the World Health Organization (WHO) in 2002, is an internationally accepted reference for disseminating information on solar UV radiation levels with the purpose of preventing the harmful ... -
Thunderstorm days over Argentina: Integration between human observations of thunder and the world wide lightning location network lightning data
(International Journal of Climatology, 2022-07)Resumen
Las tormentas son uno de los fenómenos más peligroso de la naturaleza, es por eso que conocer su distribución espacial y su evolución en el tiempo es de gran interés para la protección de la sociedad, así como para planificar ... -
Towards a South American High Impact Weather Reports Database
(Bulletin of the American Meteorological Society, 2024-04-05)Resumen
Despite Southern South America being recognized as a hotspot for deep convective storms, little is known about the socio-environmental impacts of high impact weather (HIW) events. Although there have been past efforts ... -
Validación de la estimación de precipitación por satélite aplicando la técnica Hidroestimador
(Centro Argentino de Meteorólogos, 2016-04-22)Resumen
En este trabajo, se realiza una validación cada 24 horas de la versión operativa y las versiones de prueba de la estimación de precipitación, teniendo en cuenta el periodo de un año completo de datos disponibles. Esta ... -
Validation Strategies for Satellite-Based Soil Moisture Products Over Argentine Pampas
(IEEE Geoscience and Remote Sensing Society, 2015-08)Resumen
In this paper, an evaluation strategy for two-candidate satellite-derived SM products is presented. In particular, we analyze the performance of two candidate algorithms [soil moisture ocean salinity (SMOS)-based soil ... -
Volcanic ash forecast using ensemble-based data assimilation: an ensemble transform Kalman filter coupled with the FALL3D-7.2 model (ETKF–FALL3D version 1.0)
(Geoscientific Model Development, 2020-01)Resumen
Quantitative volcanic ash cloud forecasts are prone to uncertainties coming from the source term quantification (e.g., the eruption strength or vertical distribution of the emitted particles), with consequent implications ...
