Assorted Observation Systems Meteorology 415 Fall 2011
Probing the Atmosphere • Surface • Automated Surface Observing System (ASOS) - Temp, Moisture, Pressure, Wind, Solar Radiation, Cloud Height, Precipitation, Visibility
Probing the Atmosphere • Network of Surface Hourly Observations: - FAA (1,000) - FHWA (100’s) - USDA (100’s) - DOD (100’s) - USFS (100’s) - EPA (100’s)
Probing the Atmosphere • Network of Mesoscale Observations: - State DOT (1000) - AG Nets (1000) - Private (AWS) (7000) - Utilities (100’s)
Probing the Atmosphere • Cooperative Climate Network • (10,000) • daily precip • most snow • some temp • few river gauges
Probing the Atmosphere • Cooperative Climate Network • Backbone of the nation’s climate records
Probing the Atmosphere • Historical Climate Network • (1,000 subset) • Basis of US Climate Trends
Probing the Atmosphere • Vertical Profile • Radiosonde Network (100)
Probing the Atmosphere • Vertical Profile • Atmospheric Sounding • Twice a day • Temperature • Dewpoint • Winds • Area equal to energy
Probing the Atmosphere • Vertical Profile • Profiler Network (dozens)
Probing the Atmosphere • Vertical Profile • Profiler Cross-Section • Every 6 minutes • Winds • Density (T,M)
Probing the Atmosphere • Vertical Profile • Suomi-Net (100) • Real-Time Integrated Water Content of the Atmosphere based on GPS attenuation
Probing the Atmosphere • Vertical Profile • Suomi-Net • A time series of precipitable water vapor • Related to surface flux of out-going long wave radiation • Used as a calibration for other estimates of water content
Probing the Atmosphere • Cross-Sections • ACARS – Aircraft Communications Addressing and Reporting System (4,000 daily)
Probing the Atmosphere • Cross-Sections • ACARS • Winds and Temperatures along the flight path • Important reports of Turbulence, both in cloud and clear air
Probing the Atmosphere • Horizontal – surface observing systems; hourly, daily • Vertical – weather balloons, Doppler radar, GPS • Cross-Section – Aircraft sensors
