NOAA GOES-R Series Advanced Baseline Imager (ABI) Level 2 Derived Motion Winds (DMW)

ABI-L2-DMW

browse graphicExample of the GOES-16 derived winds product.
The Derived Motion Winds product contains a list of wind vectors identifying their location, wind speed, wind direction, air pressure and temperature, and local zenith angle. The product includes data quality information for each wind vector. The product name includes the word "derived" because the wind vectors are derived by tracking environmental features, specifically clouds and clear sky water vapor over multiple ABI observations. The type of feature tracked varies as a function of the ABI band. Derived Motion Wind product files are generated for the ABI reflective and emissive band that are used to track features. The units of measure for the wind vector quantities are meters per second for wind speed; degrees for wind direction; hectopascals for wind pressure; kelvin for air temperature. Product data is produced for geolocated source data to local zenith angles of 90 degrees. The Derived Motion Winds product is produced using ABI Full Disk, CONUS, and Mesoscale coverage region observations.

Purpose The Derived Motion Winds product is derived from using a sequence of visible or IR spectral bands to track the motion of cloud features and water vapor gradients. The resulting estimates of atmospheric motion are assigned heights by using the Cloud Height product. The Derived Motion Wind product provides vital tropospheric wind information over expansive regions of the earth devoid of in-situ wind observations that include oceans and Southern Hemisphere land masses. This product provides key wind observations to operational NWP data assimilation systems where their use has been demonstrated to improved numerical weather prediction forecasts including tropical cyclones. In addition, this product provides improved guidance for NWS field forecasters.

Processing Steps
  • The Derived Motion Winds product is generated by the GOES-R ABI Derived Motion Winds ground processing algorithm. Wind speed and direction are determined by tracking environmental features, specifically cloud edges and clear sky moisture gradients, over a time series composed of three ABI observations. Two displacement vectors are produced for the two time adjacent observation pairs, and then averaged. The time associated with wind vectors in a Derived Motion Winds product file is the acquisition time associated with the middle observation. The algorithm performs several consistency checks on the derived wind information including a comparison with the NWP wind forecast to establish a confidence level for the wind vector and an estimate of its wind speed error. For each ABI band, algorithm processing occurs independently and separate product files are generated. The configuration of each retrieval is band dependent and is determined by the target type (clear sky water vapor or cloud), target box size, search window size (i.e. lag size), temporal spacing between image pairs, and the application of nested tracking of target sub-regions. This configuration information is included in the product metadata. Product files include data for each attempted wind retrieval. It is possible that one or more wind vectors in a product file have one or more null values in its data elements, which is indicated with the applicable variables' fill values. When operating in ABI mode 3, there will be a delay in the production of mesoscale Derived Motion Wind product files when the ABI is commanded to observe a new mesoscale region. This is because the algorithm requires three successive product images. The amount of delay is approximately twice the required time between successive images, which is band-specific and managed as a parameter in the Level 2+ semi-static source data. The time between successive images value is included in the product.
