FY10 Activities • Begin to identify and quantify gaps in sensor coverage • Core meteorological activities occur in this area. • Investigate sensor data format requirements for advanced data set assimilation • Begin flexible terminal architecture capability system engineering efforts
SDO Airspace – Gap ID • Gap Identification – utilize latest performance requirements, sensor assessment database and additional research to produce a detailed report of ground and airborne SDO gaps. • Portfolio of reports: • Radar – coverage, terminal winds, microburst detection • Ground sensors: ASOS, AWOS • Airborne – sensor assessment, proposed update to functional and performance requirements, gap ID.
SDO Gap ID - Radar • OEP TERMINAL AND CONUS WEATHER RADAR COVERAGE ANALYSIS FOR NEXTGEN INITIAL OPERATIONAL CAPABILITY • The initial results of a weather radar coverage analysis. • An initial step towards identifying and analyzing the sensor spatial coverage deficiencies relative to the NextGen 4D Wx SAS performance requirements.
SDO Gap ID – Wind Hazards Detection • Analysis of Ground-Based Radar Low-Altitude Wind-Shear Detection in OEP Terminal Airspace for NextGen -Submitted by MIT Lincoln Laboratory, September 1,2010 -The focus of the study is to generate 2D low-altitude microburst and gust-front visibility data to show the current and potential coverage in SDO terminal airspaces.
SDO Gap ID - Ground • Verified sensor locations recorded in several federal data bases • Radars all located within low CERs of indicated locations • ASOS sensor locations contained systematic errors • Some databases list ASOS location at airport center • Data provided by ASOS program office proved the most accurate although it still contained errors • 30% of OEP sensors not in recorded locations • Sensors moved after installation • GPS errors • Transcription errors • Updated locations will be provided when available • Still trying to locate central database of RVR locations • LLWAS locations to be verified, so far fairly reliable

Categories of Gaps • Knowledge Gap where there is not enough understanding on how to make measurements. • Engineering Gap where the technology necessary for building the needed sensor exists. • Operational Gap sensor is built and deployed for research, but time and effort are still needed to bring it to robust operational status. • Spatial Coverage Gap the spatial domain over which the requirement is defined is not completely covered. • Temporal Coverage Gap the required time coverage (e.g., 24/7) cannot be met. • Performance Gap if any of the performance requirements are not met. • Communication Gap access to the sensor product is restricted or if the data transfer infrastructure is inadequate. • Dynamic Gap temporary void due to sensor failure, network or power interruption, sabotage, or a natural disaster. • Metadata Gap hinder the proper characterization, dissemination, and usage of the sensor product.
