Abstract

Net Primary Productivity (NPP) for croplands can be estimated using a statistical method that includes factors for dry weight, harvest indices, and root:shoot ratios multiplied by yield data from the National Agricultural Statistics Service (NASS). This method has been documented and published by Prince et al. (2001), Hicke and Lobell (2004), and Hicke et al. (2004). We expanded this method by including factors for more crops and by using an estimated carbon content of 0.45 for agricultural crops to estimate (a) total net carbon uptake, (b) carbon in aboveground biomass, (c) carbon in belowground biomass, (d) carbon harvested and transported off site, and (e) the amount of carbon remaining on the surface following harvest. These five variables are included with their respective Federal Information Processing Standards (FIPS) codes for all counties in the contiguous U.S. from 1990-2005. A mean harvest efficiency of 0.95 was assumed across all crops. Total cropland NPP for the U.S. ranges from 378-527 Tg C yr-1 within years 1990-2005, and total carbon harvested and removed ranges from 161-228 Tg C yr-1 within years 1990-2005.For access to the data files, click this link to the CDIAC data transition website: http://cdiac.ess-dive.lbl.gov/carbonmanagement/cropcarbon/

Estimated Annual Net Change in Soil Carbon per US County, 1990-2004

Dataset West, Tristram ; Brandt, Craig ; Wilson, Bradly ; ...

These data represent the estimated net change (Megagram per year) in soil carbon due to changes in the crop type and tillage intensity. Estimated accumulation of soil carbon under Conservation Reserve Program (CRP)lands is included in these estimates. Negative values represent a net flux from the atmosphere to the soil; positive values represent a net flux from the soil to the atmosphere. As such, soil carbon sequestration is represented here as a negative value.
Energy Use and Carbon Dioxide Emissions from Cropland Production in the United States, 1990-2004

Dataset Nelson, R. G. ; Hellwinckel, C. H. ; Brandt, C. C. ; ...

These data represent energy use and fossil-fuel CO2 emissions associated with cropland production in the U.S. Energy use and emissions occurring on the farm are referred to as on-site energy and on-site emissions. Energy use and emissions associated with cropland production that occur off the farm (e.g., use of electricity, energy and emissions associated with fertilizer and pesticide production) are referred to as off-site energy and off-site emissions. The combination of on-site and off-site energy and carbon is referred to as total energy and total carbon, respectively.To access the older version of this data package see: http://cdiac.ess-dive.lbl.gov/carbonmanagement/cropfossilemissions/

2005 Spokane and Kootenai County Regional Travel

Dataset Team, TSDC

The 2005 Spokane and Kootenai County Regional Travel Survey is a comprehensive survey of the travel patterns of households in Spokane County, Washington, and Kootenai County, Idaho. The survey was conducted for the Spokane Regional Transportation Council over a three-month period from April through June 2005. The data are drawn from 1,828 households within Spokane and Kootenai counties and contain information about 4,488 household members, 3,974 vehicles, and 19,638 trips made during a 24-hour period. The survey relied on the willingness of study area residents to 1) provide demographic information about their household, its members, and its vehicles during themore »« less
2005 Washoe County Travel Characteristics Study

Dataset Team, TSDC

The primary objective of the 2005 Washoe County Travel Characteristics Study was to document travel behavior data characteristics of regional households in Washoe County, Nevada, in order to update the regional transportation model. The household travel survey, which was conducted from October through November, was one of several surveys conducted in the fall of 2005 for the Regional Transportation Commission (RTC) of Washoe County, with the other surveys focusing on documenting transit usage, visitor travel behavior, and external travel through the region. The data collected were drawn from 1,174 households within the RTC planning area and contain information about 2,679more »« less
