Global interannual trends and amplitude modulations of the sea surface height anomaly from the TOPEX/Jason-1 altimeters
(AMER METEOROLOGICAL SOC, 2008)
This study uses the global Ocean Topography Experiment (TOPEX)/Jason-1 altimeters` time series to estimate the 13-yr trend in sea surface height anomaly. These trends are estimated at each grid point by two methods: one ...
Uso de sombras na correção do efeito vinhete
(2014-01-01)
When registering spectral radiance from surface targets, digital numbers recorded by the imagery sensor may vary. Such variation causes imperfections on the images coming from aerial surveys. Variation in the image brightness ...
Sea surface height trend and variability at seasonal and interannual time scales in the Southeastern South American continental shelf between 271S and 401S
(Elsevier, 2014-12)
Recent improvements in satellite altimetry data correction terms are encouraging studies of the remote sensed Sea Level Anomalies (SLA) progressively closer to the coast and over shallow continental shelves. In this paper ...
Wind speed trends over the Southeastern continental shelf of South America, between 33° and 50° S
(John Wiley & Sons Ltd, 2016-01)
Surface scalar wind speed trends (from 1979 to 2009) at the southwestern Atlantic Ocean, between 33° and 50°S and 55° and 70°W, were estimated from the NCEP/NCAR I (NR1) and the Climate Forecast System Reanalysis (CFSR) ...
Evolution and population structure of africanized honey bees in Brazil: Evidence from spatial analysis of morphometric data
(Soc Study Evolution, 1995-12-01)
In recent years, studies based on isoenzymatic patterns of geographic variation have revealed that what is usually called the Africanized honey bee does not constitute a single population. Instead, several local populations ...
Honey Ants (Genus Myrmecocystus) Macroecology: Effect of Spatial Patterns on the Relationship between Worker Body Size and Geographic Range Size
(1998-10-01)
Macroecology evaluates the partitioning of physical space and resources among organisms through correlation among ecological variables, such as geographical range size and shape, body size, and population density, measured ...
Detecting trends in time series of functional data: a study of antarctic climate change
(Wiley, 2014-12)
The Spanish Antarctic Station Juan Carlos I has been registering surface air temperatures with the frequency of one reading per ten minutes since the austral summer 1987-88. Although this data set contains valuable information ...
110 years of temperature observations at Orcadas Antarctic Station: multidecadal variability
(John Wiley & Sons Ltd, 2015-06)
There is growing evidence of significant changes in components of the Antarctic climate system, an important issue given the influence Antarctica has on global climate. It is important to infer to what extent these regional ...
