L-band scintillations and calibrated total electron content gradients over Brazil during the last solar maximum
(Edp Sciences S A, 2015-12-08)
This work presents a contribution to the understanding of the ionospheric triggering of L-band scintillation in the region over Sao Paulo state in Brazil, under high solar activity. In particular, a climatological analysis ...
Characterization of climatological time series using autoencoders
(Universidad La Salle, 2017-11-08)
Common problems in climatological time series data are high dimensionality, correlation between the sequential values and noise due to calibration of meteorological stations influencing dramatically in the quality of ...
A study of persistence analysis in climatic data from Salvador – Brazil
(2011)
Fractal geometry has been used frequently to characterize and describe natural models. Its
applications range from microscopic dimensions to the understanding of macroscopic processes. Following this principle, we studied ...
Wind waves climatology of the Southeast Pacific Ocean
(Wiley, 2017)
The climatology of wind waves over the Southeast Pacific is analysed using a 32-year hindcast from the WaveWatch III model, complemented by satellite-derived significant wave height (SWH) and buoy measurements for validation. ...
GEOESTATISTICS APPLIED TO SPATIAL DISTRIBUTION OF THE PRECIPITATION
(Univ Estadual Paulista Julio Mesquita Filho, 2016-01-01)
The spatial distribution of certain climatic element from collected sample points is a usual task in Climatology. However, the phenomenon generally presents spatially correlated so that there is a need to use an interpolation ...
Climatologia de frentes frias no litoral de Santa Catarina
(2004-05-01)
A climatology of cold fronts at the coast of State do Santa Catarina, Brazil, is established based on 10-year period (1990-1999) of NCEP-NCAR reanalysis data. The cold front passages were objectively identified taking into ...
Assessing the GNSS scintillation climate over Brazil under increasing solar activity
(2013-12-01)
We study ionospheric scintillation on GNSS signals at equatorial latitudes to draw a climatological picture of the low latitude ionosphere in the Brazilian sector during the ascending phase of the upcoming 2013 solar ...
A seasonal climatology of UV reflectivity for southern South America
(Taylor & Francis Ltd, 2017-10)
A seasonal climatology for the Lambertian equivalent reflectivity (LER) in ultraviolet (UV) for southern South America is introduced. The study region was limited by 10° and 60°S and by 100° and 30°W; the data set spanned ...
