TerraME observer: extensible real-time visualizations of dynamic spatial models.

This paper presents ongoing research results of an extensible visualization pipeline for real-time exploratory analysis of spatially explicit simulations. We identify the software requirements and discuss the main conceptual and design issues. We propose a protocol for data serialization, a high per...

Simulation of the impacts land use and land cover changes – LUCC on the hydrological response of the Ji-Parana Basin with MGB-INPE model.

Hydrological response results from innumerous processes interacting at different spatial and temporal scales and with various intensities. Since the hydrological impacts of Land use and land cover change (LUCC) and climate variability (CV) are strongly dependent on soil water flow pathways, an adequ...

Modis time series for land use change detection in fields of the amazon soy moratorium.

A virtual globe to visualize time series of pixels from the MODIS sensor over the South American continent is available in the Internet and was developed at the Brazilian Institute for Space Research. The MODIS images acquired since the year 2000 were transformed to a vegetation index (EVI2, two-ban...

Geographical variations of negative cloud-to-ground lightning parameters: a review.

This paper reviews the information available on the dependence of negative cloud-to-ground (CG) lightning characteristics on geographical location. From the information available in the literature at the present time, there is no conclusive evidence of a significant dependence of negative CG lightni...

The sensitivity of the thunderstorm activity in the city of São Paulo to temperature changes: predicting the future activity for different scenarios.

Thunderstorms are part of the complex and interactive processes that form the climate. Its variability can arise from a number of factors, some internal others external to the climate system. In consequence, our ability to predict future climate changes in the thunderstorm activity depends on a bett...
