Instuctions

Main Satellite Comparison tab

  • Start by choosing two existing or near-future satellites to compare using the drop-downs.
  • Examine the Detection, Temporal, and Spatial sub-scores for the selected satellites and how they combine in an overall completeness score.
  • View important satellite details, such as minimum detection limit, for the selected satellites in the “Instrument Parameters” box.
  • Explore the effects of different World Assumptions (such as increasing or decreasing assumed emissions persistence) by adjusting them at the top of the page.
  • Scroll down to observe how more than 10 existing satellite missions compare in terms of completeness (based on selected World Assumptions).

Edit Custom Satellite

  • Use the “Edit Custom Satellite” feature to create your own instrument.
  • Enter the minimum detection limit (MDL) and daily coverage for your new satellite or use the provided calculator to generate a daily coverage.
  • Explore the effects of different World Assumptions (such as increasing or decreasing assumed emissions persistence) by adjusting them at the top of the page.
  • See how user-entered satellite details and selected World Assumptions affect the Detection, Temporal, and Spatial Completeness sub-scores using the charts on the right.
  • Save your Custom Satellite to compare it to preloaded satellites on the Main Comparison tab.
