Solar forecasts based on the clear sky index or the clearness index: which is better?
(2022)
In the realm of solar forecasting, it is common to use a clear sky model output to deseasonalise the solar irradiance time series needed to build the forecasting models. However, most of these clear sky models require the ...
Daily Global and diffuse radiation in the Brazilian Cerrado-Amazon transition regionRadiação global e difusa diária na região de transição Cerrado-Amazônia brasileira
(Universidade Federal de Santa Maria, 2021)
Annual evolution of global, direct and diffuse radiation and fractions in tilted surfaces
(Associação Brasileira de Engenharia Agrícola (SBEA), 2014)
Wind-profiling doppler radars for tropical atmospheric research
(American Geophysical Union, 1990-12)
The past decade has seen a rapid increase in the use of wind profilers in atmospheric research [Gage, 1990]. Briefly, wind profilers are Doppler radars that observe winds from Doppler shifts of "clear air" atmospheric ...
Inter-annual variability in snow cover depletion patterns and atmospheric circulation indices in the Upper Irtysh basin, Central Asia
(Wiley, 2020)
The Irtysh River is the main water resource of Eastern Kazakhstan and its upper basin is severely affected by spring floods each year, primarily as a result of snowmelt. Knowledge of the large-scale processes that influence ...
The atmospheric circulation associated with extreme rainfall events in Piura, Peru, during the 1997-1998 and 2002 El Niño events
(European Geosciences Union (EGU), 2004-11-29)
The lowland of Piura, in northwestern Peru, is very strongly impacted by El Niño. Its climate is arid but can experience very heavy rainfall associated with the high nearby sea surface temperature (SST) during El Niño ...
Practical models to estimate horizontal irradiance in clear sky conditions: preliminary results
(Elsevier, 2010-11)
The Argentinean Northwest (ANW) is a high altitude region located alongside Los Andes Mountains. The ANW is also one of the most insolated regions in the world due to its altitude and particular climate. However, the ...
Annual evolution of global, direct and diffuse radiation and fractions in tilted surfaces
(Associação Brasileira de Engenharia Agrícola (SBEA), 2012-04-01)
Avaliou-se a evolução anual das componentes global, direta e difusa da radiação solar incidente em superfícies inclinadas a 12,85; 22,85 e 32,85º, com face voltada ao Norte, em Botucatu-SP. Foram obtidas frações radiométricas ...

Index of thermal stress for cows (ITSC) under high solar radiation in tropical environments
(Springer, 2015-05-01)
This paper presents a new thermal stress index for dairy cows in inter-tropical regions, with special mention to the semi-arid ones. Holstein cows were measured for rectal temperature (T-R), respiratory rate (F-R) and rates ...
