CanVis is a visualization program used to see potential impacts from coastal development or sea level rise. Users can download background pictures and insert the objects (hotel, house, marina, or other objects) of their choosing. The free PC-based software is used by municipalities to brainstorm new ideas and policies, undertake project planning, and make presentations.
This year's theme for the annual forum held in Washington, DC is “the value and sustainability of the weather, water and climate enterprise.” Recent research indicates that the annual economic impact of weather events is as much as $485 billion in the United States.
Global climate is changing, and this is apparent across the U.S. in a wide range of observations. Rising temperatures, changes in precipitation and extreme events and their causes and impacts on society and the environment are chronicled in the 2013 National Climate Assessment. A team of over 240 experts compiled the report, which is open for public comment through April 12, 2013.
Climate normals are the average values of meteorological parameters -- such as temperature, precipitation, frost/freeze data, and snowfall data -- over 30-year spans. The climate normals data help describe typical climate conditions for a given place and time of year, and are used as a baseline to which current conditions can be compared.
The National Solar Radiation Database contains 30 years (1961-1990) of solar radiation and supplementary meteorological data, and hourly solar radiation and meteorological data for 237 National Weather Service sites in the United States, Guam, and Puerto Rico. Also includes maps of the monthly amounts of solar power that could be generated with various solar collectors.
Local Analysis and Prediction System (LAPS) Solar Energy Forecast
December 28, 2012
The LAPS system produces rapidly updated, high-resolution analyses and forecasts of solar radiation. The cloud analysis uses satellite, METARs, radar, aircraft, and model first guess information to produce an hourly 3-D field of cloud fraction, cloud liquid, and cloud ice. The cloud analysis and satellite data together are used to produce a gridded analysis of total solar radiation.
Carbon Dioxide Information Analysis Center (CDIAC)
December 28, 2012
The CDIAC is the primary global-change data and information analysis center of the U.S. Department of Energy (DOE). It contains information on concentrations of carbon dioxide and other radioactively active gases in the atmosphere; the role of the terrestrial biosphere and the oceans in the biogeochemical cycles of greenhouse gases; emissions of carbon dioxide to the atmosphere; long-term climate trends; the effects of elevated carbon dioxide on vegetation; and the vulnerability of coastal areas to rising sea level.
Voluntary Reporting of Greenhouse Gases-Carbon Management Evaluation Tool
December 28, 2012
A decision support tool for agricultural producers, land managers, soil scientists and other agricultural interests, COMET-VR estimates soil carbon changes for management alternatives for a ten-year projection period within each Major Land Resource Area (MLRA) allowing users to estimate soil carbon sequestration on a parcel of land. The COMET-VR tool is provided by the U.S. Department of Agriculture.
Twice per day NOAA's National Weather Services publishes digital maps that show national forecasts for ozone, smoke, and dust. Ozone is shown as 1-hour and 8-hour concentrations. Official Air Quality point forecasts, issued by state and local air quality forecasters, along with additional information on air quality can be found under EPA's AIRNow site. Surface and column-averaged concentrations of predicted smoke for large fires are displayed as 1-hour averages, updated each day.
