Abstract. Fires associated with land use and cover changes release large amounts of aerosols trace gases into the atmosphere. Although several inventories biomass burning emissions Brazil, there are still considerable uncertainties differences among them. While most fire emission utilize parameters burned area, vegetation fuel load, factors, other to estimate its emissions, more recent apply an alternative method based on radiative power (FRP) observations amount corresponding aerosols. The...
Abstract. We present a new version of the Brazilian developments on Regional Atmospheric Modeling System (BRAMS), in which different previous versions for weather, chemistry, and carbon cycle were unified single integrated modeling system software. This also has set state-of-the-art physical parameterizations greater computational parallel memory usage efficiency. The description main model features includes several examples illustrating quality transport scheme scalars, radiative fluxes...
In developing countries, accurate rainfall estimation with adequate spatial distribution is limited due to sparse rain gauge networks. One way solve this problem the use of satellite-based precipitation products. These satellite products have significant coverage estimates and it fundamental importance investigate their performance across space–time scales factors that affect uncertainties. open literature, some studies already analyzed ability estimate average values. investigations found...

Rainfall measurement is a very important topic to society and for the understanding of weather climate, therefore needs be calculated as accurately possible. Counteracting problem high temporal spatial variability precipitation, geostationary satellites sensors have been proved an excellent tool this task, providing scans with resolution detecting growth decay rain cells. Using infra-red (IR) images obtained from Geostationary Operational Environmental Satellites (GOES), Hydro-Estimator...
Multifilter rotating shadowband radiometer (MFRSR) calibration values for aerosol optical depth (AOD) retrievals were determined by means of the general method formulated Forgan [Appl. Opt.33, 4841 (1994)] at a polluted urban site. The obtained precision is comparable with classical method, Langley plot, applied on clean mountaintops distant pollution sources. AOD retrieved over São Paulo City both procedures compared Aerosol Robotic Network data. observed results are similar, and, except...
The knowledge of the diurnal cycle precipitation is extreme relevance to understanding physical/dynamic processes associated with spatial and temporal distribution precipitation. main difficulty this task lack surface information over certain regions on an hourly time scale low representativeness these data (normally gauges). In order overcome difficulties, objective study create a 3-h accumulation database from gauge-adjusted daily regional products resolve properly. This also proposes...
