Introduction to TAMDAR Data Integration: Enhancing RUC Model Accuracy

This document provides an overview of the TAMDAR (Tropospheric Airborne Meteorological Data Reporting) system, focusing on its integration into the RUC (Rapid Update Cycle) models. Key presentations by Bill Moninger, Stan Benjamin, and others highlight the significance of TAMDAR soundings, differences in RUC models with and without TAMDAR data, and results demonstrating improved RUC skills. Additionally, it discusses the FSL infrastructure for processing and distribution of aircraft data and available resources for soundings and statistics. This is essential for understanding the presented improvements and functionalities.

Presentation Transcript

  1. FSL Work on TAMDAR/GLFE • This introduction - Bill Moninger • Description of RUC-TAMDAR models - Stan Benjamin • A look at TAMDAR soundings - Ed Szoke • RUC differences with and without TAMDAR - Brian Jamison • RUC Skill results - Stan and Bill • Processing and Distribution - Mike Barth

  2. FSL Infrastructure developed for the GLFE (1) • Aircraft display (http://acweb.fsl.noaa.gov/) • shows Wind, T, Td, RH, Turbulence, Icing • TAMDAR and non-TAMDAR can be selected • Soundings displays • available from aircraft display • available as separate page • (http://www-frd.fsl.noaa.gov/soundings/java/)

  3. ‘Select’ option allows you to select TAMDAR only

  4. FSL Infrastructure (2) • MADIS distribution system provides TAMDAR and other aircraft data for • ingest into local models • display on AWIPS • Mike Barth will discuss this in more detail

  5. FSL Infrastructure (3) • Aircraft-RUC database • stores 1h forecasts from the operational RUC at EMC interpolated to aircraft data points • Partial output available at • http://acweb.fsl.noaa.gov/ruc_acars/ • Daily statistics by FSL aircraft ID • Weekly statistics • Interactive statistics • Detailed data available for internal analysis; I’ll present results later

  6. Statistics for 23-March-2005 from http://acweb.fsl.noaa.gov/ruc_acars/daily_stats/

  7. FSL Infrastructure (4) • Matched real-time RUC models • “dev” does not include TAMDAR • “dev2” includes TAMDAR • otherwise dev is identical to dev2 • Stan will discuss this in more detail
