Summary

The RADAMBRASIL project extensively mapped the Amazon soils using a combination of soil pit information, aerial photography, and geologic maps. During the project, 1,153 soil pits, distributed basin-wide, were described and sampled by horizon and analyzed for texture and chemical composition.

This data set, which consists of one file in ASCII comma separated format, contains soil profile descriptions for locations throughout Brazilian Amazonia. These data are based on RADAMBRASIL surveys from the Soil Profiles of Amazonia (Source: IPAM, Brazil/WHRC, USA ). See the companion file Soil_Profiles_of_Amazonia.pdf.

A Complementary Soil Profile Database

A more recent complementary database of Brazilian Soil Profiles has been compiled by Cooper et al. (2005). In addition to the RADAM survey volumes covering the Amazon region included in this data set, Cooper et al. have also compiled profiles from all the soil survey volumes of RADAM, EMBRAPA, SUDENE, SUDAM, etc. for all regions of Brazil. The database contains 5,500 soil profiles. However, they only included data for the soil A horizon and the diagnostic B horizon and did not include all of the descriptive information for the profiles that is included in this data set.

Pre-LBA Data Set Collection Initiative

The data in the documented Pre-LBA Data sets were originally published as a set of three CD ROMs (Marengo and Victoria, 1998) but the individual data products are now archived separately. The RADAMBRAZIL soil profile data file provided on the CD ROMs was not useable due to inconsistencies with profile identification and coordinates.

The Pre-LBA data set collection was dedicated to providing information to the LBA research community about existing data that have been collected in Amazonia during the 20 years prior to 1998. The main goal of this activity was to compile and document existing data sets in a consistent manner and make them available prior to the beginning of the LBA experiment.

The data set compilation efforts included satellite imagery, micrometeorological observations, near surface and upper-air atmospheric conditions, surface biophysical and hydrological measurements obtained from 1970s – 1990s in a number of field experiments.  Data were collected for several intensive field campaigns, during the rainy and dry seasons, and other periods that vary from short intensive field campaigns to several years worth of observations, measured sometimes with a time resolution of 5 minutes and 1 hour.

Missing Value Notes:

In the investigator provided data file, missing values for numeric fields were represented by several different character codes. These codes were converted to distinct negative numeric values. It was not apparent from the original documentation if there were important distinctions among the missing value codes. Subsequent users may choose to set all numeric missing values to a common code for convenience.

Investigator provided missing value codes Converted values Comments
“-“ for data values reported as integers -999  
“-“ for data values reported with decimals -999.999 Latitude and Longitude
“blank cell” for data values reported as integers -888  
“blank cell” for data values reported as characters Not_available Map_Sheet and Parent_Material
“X” for data values reported as integers -777  
In the column “Areia_Grossa” (Coarse Sand) the character values “T.areia” ( and variations) -666 It appears that when column “Areia_Grossa” (Coarse Sand) = “T.areia” then both Calhau(Coarse Gravel) and Cascalho (Gravel) are missing and Areia_Fina, Silte, and Argila (Fine_Sand, Silt, Clay) total to 100%.

RADAMBRASIL Background

In 1970, the RADAMBrasil project started its collection of airborne radar images and photographs over an extensive area of Brasil. The equipment and data collection effort were designed to map sections of the Brazilian territory. An altimeter recorded altitude variations that were registered and used to produce a three-dimensional relief map of the Brazilian areas. Over the 15 year period of 1970 to 1985, the Radambrasil instrumention imaged and photographed each section of the country. With this instrumentation, a team of geographers and cartographers from the University of São Paulo (Sao Paulo, Brazil), led by Prof. Jurandyr Luciano Sanches Ross, compiled a compendium of information showing the diverse physical aspects of Brazilian territory. The final product helped in redefining the existing Brazilian relief maps.
