Presentation of GSICS Inter-Calibration Results - Web Displays Tim Hewison

Scope Review of Current Static Web Displays Revised NetCDF Format for Results GSICS Correction Coefficients Possible Dynamic Generation of Plots

Example Collocation Map

Example Regression Scatter plot

Example Time Series of Tb Bias

Parameters of Static Web Displays Collocation Maps Regression Scatter plots With Error bars? Thinned? Time Series of Tb bias at Tbstd Period? <=1yr? Daily, ‘Monthly’ Trends, ‘resets’ (alerts) Multiple Standard Radiances? Regression Coefficients? Download Correction Coefficients NetCDF format Not available yet

Revised NetCDF format for Inter-Calibration Results

Plots, Tables, Trends, Anomalies Generic Data Flow Plots, Tables, Trends, Anomalies Collocation Maps Generated in Step 1 Static Plots and Tables of Regression scatter plots and Time Series of Tb Bias Generated in Step 4 ‘Statistical Data’ Include Correction Coeffs Revised NetCDF format Dynamic Plots Generated on web server from ‘Statistical Data’ Coefficients and Algorithm Supplied to Users 5. GSICS Correction

Dynamic Generation of Plots Graphs generated on demand on server: From series of daily results files Thousands of small files Or cumulative results file, updated daily One larger file, including time as coordinate variable Or some compromise (e.g. annual to date) Allow User Selection of: Instrument(s), Channel(s) – Allow comparisons? Start, End Date Standard Radiances Time series Plots or Tables of Daily results or Smoothed results All GPRCs could use same code If all results files have same format Allow comparisons of algorithms?
