For more than a century, the National Weather Service (NWS) and other federal agencies have relied on a network of thousands of volunteers across the country to gather data on climate and weather such as rainfall, snowfall, and temperature. Operating on an annual budget of less than $10 million, the Cooperative Observer Network provides information for making daily and weekly forecasts, monitoring water resources, and charting environmental changes. Businesses also use the data for decisions such as where to plant crops or build a power plant.
But despite growing demand for the data, organizational and budgetary constraints have weakened the network over the last decade. More funding is needed to maintain operations and upgrade instruments -- many of which have not changed significantly in years, says a new report by a panel of the National Research Council. By improving management and gradually automating more data collection and communications functions, the network could become well-positioned to serve the nation into the next century.
Government agencies that use the network's data, for example the U.S. Army Corps of Engineers and the departments of Agriculture and the Interior, often are delayed in getting the information they need because of inefficient and slow data reporting, obsolete equipment, and differences in priorities between NWS and the National Climatic Data Center, another government entity that processes and disseminates data from the network.
To make data available quickly and improve accuracy, the report says, new weather monitoring equipment that can automatically measure weather factors should be introduced gradually and tested at selected sites. Automating data collection would reduce heavy demands on volunteers, but they will still be needed to oversee equipment and observations and to supply information -- such as snow depth and precipitation -- that cannot be measured fully with existing technology. NWS already has begun installing electronic temperature measuring systems at many of the volunteer sites. Other technologies, including sensors to measure humidity and solar radiation, could be added to bolster the network's capabilities.
In addition, upgraded real-time digital communications systems should be installed to allow volunteers to report data on at least a daily basis, the panel said. Volunteers now gather two types of data -- climate data, such as daily temperatures, precipitation, or snowfall; or hydrologic information for river and flood forecasting. Depending on the data and the technological capabilities of the volunteer sites, information might be reported daily to NWS offices or submitted less frequently by mail. NWS staff must process the information before making it available to other users. Fully automating data reporting would give other users more frequent and faster access to information.
Some local or regional networks outside of the cooperative observer system should be considered as sources of data to augment the observer system's efforts, the report says. For example, two universities in Oklahoma operate a statewide network of environmental monitoring stations that measure temperature, wind speed, and other factors at more than 100 sites. These types of networks could enhance the cooperative's capabilities if the data meet established standards.
The National Oceanic and Atmospheric Administration (NOAA) -- which houses the National Weather Service and National Climatic Data Center -- should establish an office that would ensure the cooperative network is properly managed and funded, the report says. The central office should make the observer network a high priority within NOAA and with other agencies that use the data. In addition, NOAA should work with other agencies to establish an interagency management council to involve federal users in planning, policy-making, and funding. Industry and other users from the private sector also may need to provide more funding to upgrade the system. To recover costs, fees should be charged for processing and copying the data or making it available over the Internet.
