  • MMAPS

    Gradient MMaps is a program that displays forecast maps of regions where radio propagation at VHF, UHF frequencies are forecasted to be disturbed by conditions in the atmosphere.

  • PUFF

    PUFF models the dispersion of volcanic ash from an eruption. A series of "ash" files in Network Common Data Format, describing ash distribution over time. Also available is the display of ash distribution overlaid on a geographical map.

  • APG

    The APG produces atmospheric profiles and target to sensor spectral transmittance in seconds for true target radiance determination over any MM5 theater area.

  • SRG

    The SRG produces at-sensor spectral radiance for time-critical hyperspectral applications, based on imported surface reflectance/emissive libraries as well as radiosonde or MM5 weather forecast data.

  • SARwind

    This software package generates a high-resolution blended coastal wind product using the Air Force Weather Agency's MM5 10-m wind direction forecasts to derive wind speeds from RADARSAT-1 synthetic aperture radar imagery.

  • Dust Transport Application

    CARMA-Dust (Community Aerosol Research Model from Ames/NASA) is a model for the forecast of dust storms and the prediction of dust concentration in the atmosphere.

    The model makes a 72 hour forecast of dust including the effects of winds, dust particle size and surface moisture using MM5 forecast data. The output of the CARMA model is a set of colored maps showing the total dust concentration (µg/m3) at user selected heights above ground and total dust load in the atmosphere (µg/m3).

  • Surface Dust Flux Model

    The Surface Dust Flux modeling software package uses forecasted surface winds to estimate the rate at which ground level dust is being produced from source areas within a mesoscale theater. The model uses MM5 forecasted wind fields, soil moisture, and estimated precipitation as input. It can make forecasts for 2 MM5 mesoscale regions covering Northern Africa and the Middle East (T9z) and Southwest Asia (T4y). The surface dust fluxes are displayed as regional maps with color overlays.

  • Contrail Forecast Techniques

    A conventional theory of mixing clouds and aircraft specific contrail factors are used to analyze the formation of condensation trails (contrails). Forecasts of contrail layers are calculated with the Airforce Weather Agency's (AFWA) 5th generation Mesoscale Model (MM5). Products are charts showing profiles of the atmosphere including the actual contrail layers and the evolution of contrail layers for the test-site, Fairbanks/Alaska.

  • Polar Stratospheric Clouds (PSCs)

    The Polar Stratospheric Clouds Detectability model produces daily forecasts of PSCs in the lower stratosphere using AFWA MM5 weather data. The model produces color maps showing PSC probabilty at high latitudes, using either fixed or climatological values of HNO3 and H2O mixing ratios.
