Description:
Abstract:
This data set illustrates the clean air sector utilized by the National Oceanic Atmospheric Administration (NOAA) Climate Monitoring and Diagnostics Laboratory (CMDL) at Point Barrow, Alaska. The clean air sector is described as north-northeast to southeast from the NOAA CMDL Tower.
Purpose:
This GIS data set was developed to illustrate the clean air sector for use in the BEO Science Research District Master Plan.
Supplemental_Information:
The Climate Monitoring and Diagnostics Laboratory (CMDL) of the National Oceanic and Atmospheric Administration, conducts sustained observations and research related to source and sink strengths, trends and global distributions of atmospheric constituents that are capable of forcing change in the climate of Earth through modification of the atmospheric radiative environment, those that may cause depletion of the global ozone layer, and those that affect baseline air quality. CMDL accomplishes this mission primarily through long-term measurements of key atmospheric species at sites spanning the globe, including five fully-equipped Baseline Observatories. These key species include carbon dioxide, carbon monoxide, methane, nitrous oxide, surface and stratospheric ozone, halogenated compounds including CFC replacements, hydrocarbons, sulfur gases, aerosols, and solar and infrared radiation. The measurements are of the highest quality and accuracy possible, and document global changes in key atmospheric species, which are all affected by mankind, identifying sources of interannual variability. In addition, research programs in key regions, utilizing an array of platforms including aircraft, balloons, ocean vessels and towers, complement the land-based information. CMDL's data are used to assess climate forcing, ozone depletion and baseline air quality, to develop and test diagnostic and predictive models, and to keep the public, policy makers, and scientists abreast of the current state of our chemical and radiative atmosphere.

Data_Quality_Information:
Attribute_Accuracy:
Attribute_Accuracy_Report: Attributes were automatically generated by ESRI GIS software.
Quantitative_Attribute_Accuracy_Assessment:
Attribute_Accuracy_Value: good
Attribute_Accuracy_Explanation: The attributes associated with this file are the ESRI defaults.
Logical_Consistency_Report:
The bearing and range for the clean air sector were plotted from a high precision GPS coordinate taken for the NOAA CMDL Tower. This information was correlated with georeferenced IKONOS satellite imagery in ArcGIS to verify the locational information.
Completeness_Report:
The clean air sector was prepared with the best available data as of August, 2003. NOAA CMDL annual reports were checked and the sector was visually confirmed by the station chief, Dan Endres.
