Q2. Which of the following is true about CALMET?
1) Grid spacing can be varied within the domain.
2) Meteorological characteristics can be specified in multiple vertical layers.
3) Terrain and land use is specified.
4) All of the above

Overwater Data
Buoy Data:
Data used to define conditions over water portions of the modeling domain:
1. Wind
2. Temperature
3. Stability
4. Dispersion
Copyright 2003-2014 – Lakes Environmental Software 1-20
Computational Grid
1. Smaller or equal to the Met Grid
2. Once puff leaves the Computational Grid it is “forgotten” (erased)

Reasons to Split
Very Big Puff (tracked > 12 hrs)
1. Horizontal winds (mostly at night – less convective)
2. Vertical splitting
3. Independent movement
4. Lower Maximum Impact
Very Long Puff
1. Horizontal splitting
2. Small grid spacing
