ARIs Job Sheet 2

Jobsheet #2: Loading ARI data in the FFMP Basin Table (and FFMP D2D display)

  1. Load FFMP for any precip source (e.g. SCAN-> FFMP $radar Table/Basins DHR Display; Fig. 1 ).
    • e.g. SCAN-> FFMP klot Table/Basins DHR Display for the klot DHR Legacy precip source
  2. Click on the Attributes button on the upper-right part of the FFMP table (Fig 2).
  3. If the ARIFFG1 checkbox is selected, deselect it, and select ARIFFG10 (Fig 3).
    • Three new columns will appear: basin-averaged ARI, Ratio based on QPE-to-ARI, and Diff based on ARI - QPE.
  4. Each additional ARI checked from the Attributes table will add three more columns to the table.
    • Deselecting the checkbox before selecting the next checkbox is a convenient way to cycle through each of the ARIs to compare ARI precip to the QPE for the basins in the table.

 

Next let's change the display of the FFMP D2D to show ARI-based calculations.

  1. In the FFMP table, go to the D2D menu, and select ratio. Note the RFCFFG is checked on the bottom of the menu (Fig 4).
  2. Select one of the check boxes for ARI (e.g. ARIFFG25) and notice the changes in the D2D display (Fig 5).
  3. To return the D2D display to FFG, select RFCFFG in the D2D menu (Fig 6).
