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


Met Stations Data

Meteorological Preprocessor (Observation Data)

Surface

HUSWO)

Upper Air

Overwater

Data - Buoy

(Optional)

Output File:

SURF.DAT

Output File(s):

UP1.DAT,

UP2.DAT…

Output File:

PRECIP.DAT

Output File(s):

SEA1.DAT,

SEA2.DAT...


Overwater Data

Buoy Data:

Data used to define conditions over water portions of the modeling domain:

1. Wind

2. Temperature

3. Stability

4. Dispersion


Computational Grid

1. Smaller or equal to the Met Grid

2. Once puff leaves the Computational Grid it is “forgotten” (erased)

Met Grid Computational Grid


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
