Monthly Modeling Tip

Map Projection Systems
in CALPUFF
|
The spherical shape of the earth requires the use of a map projection system
to translate a given site onto a flat domain (flat map). The selection of the
appropriate map projection system will ensure that map features such as terrain,
borders, roads, etc, are not severely distorted when a site is represented on a
Cartesian plane.
The Universal Transverse Mercator (UTM)
and the Lambert Conformal Conic (LCC) are the two most commonly
used map projection systems in CALPUFF modeling projects.
When Should LCC Projection Be Used in CALPUFF?
The UTM map projection system is generally used in
short-range air dispersion modeling projects such as ISCST3 and AERMOD.
For long-range models, such as CALPUFF, the option of using the Lambert
Conformal Conic (LCC) map projection becomes more suitable when:
a) The source-receptor distance >100 km
b) The site is located in or above mid-latitudes (e.g., 48 degrees)
How to Convert
an Existing CALPUFF UTM Projected Site Domain into
an LCC Projection?
Sometimes, a CALPUFF project that is initially created in the
UTM map projection system needs to be converted into the LCC
projection system. The conversion, in this case, will follow
the general scheme shown below:
Three points on the UTM projected site are critical in
the conversion process:
• The center of the domain: this can represent the
projection origin in the LCC projection system.
• The south-west corner (SW corner): this can represent
the 1st standard parallel in the LCC projection system.
• The north-east corner (NE corner): this can represent
the 2nd standard parallel in the LCC projection system.
Once these three points are noted, the
following two-step process converts the site domain into
the LCC projection:
Step 1: The UTM coordinates of each of
these three points should be entered into a geographical
coordinate converter
and the corresponding geographical coordinates (latitude/longitude)
of each point should be noted. When converting UTM coordinates
into geographical coordinates, the following parameters
are necessary:
• UTM X and Y coordinates
• Datum
• UTM zone
• Hemisphere
Step 2: The next step is to specify the appropriate LCC
parameters for your site domain by ensuring that:
1. Datum: Specify the datum to be used for the LCC Projected
site (e.g. NAD83, WGS84). The majority of the time this
is the same datum of the UTM projected site.
2. Standard Parallels: The latitude of the ‘SE corner’ and
the ‘NE corner’ are entered as the standard
parallels.
3. Projection Origin: The latitude/longitude coordinates
of the center of the domain are entered as the projection
origin.
4. False Easting and Northing: The false
easting (X) and northing (Y) are offsets (in meters) that
enable the domain
to have positive coordinates in both directions. If an
offset is not required, specify (0,0).
Note: Once
the above steps are completed, the site domain of your
project is successfully converted to the LCC projection
system. However, the corresponding LCC coordinates of the
following objects within the site have to be determined
(from existing UTM coordinates):
• Grids
• Sources
• Receptors
• Buildings
These conversions can be done by using a coordinate converter.
Make sure to specify the same LCC projection parameters
(parallels, origin, false easting, false northing and datum)
in the coordinate converter as used in your CALPUFF LCC
Projection (see Step 2).
CALPUFF View Users: CALPUFF
View offers a tool that allows for several types of coordinate
conversions. This Coordinate Converter utility is available
under the Tools menu. In CALPUFF View, you can specify
the LCC projection parameters (e.g., projection origin,
standard parallels, and false easting and northing) in
the Site Domain dialog.
Other Users: Several
websites offer coordinate converter tools (click
here for
an example).

Pollution Prevention Programs Across
the U.S. Prevent 6 Billion Pounds of Pollution
A survey conducted by the National
Pollution Prevention Roundtable (NPPR) has found that
from 2001 to 2003, 29 pollution prevention programs
in the United States prevented 6 billion pounds of
pollution, reduced energy usage by 1.2 billion kilowatt
hours, and conserved over 44 billion gallons of water.
As a result of these measures, cost savings for these
29 programs added up to over $500 million.

Brazil Sees Amazon Land Clearing Easing This Year
Huge tracts of Brazil's Amazon rainforest were cleared
legally and illegally in the past year, but the rate
of deforestation slowed, the country's environment
minister said Tuesday. It was the second year in a
row that the pace of the destruction of the world's
largest tropical rainforest declined. Booming demand
for farm exports caused land-clearing to peak in 2004.

Manitoba to Quadruple Wind Power on Market Demand
Manitoba will issue a call for 300

Getting Religious about Air Pollution?
Stephen Weber studies the effect
large cities have on the local atmosphere. However,
a couple of years ago a newspaper article distracted
him from his research. The story detailed new findings
by scientists in The Netherlands who reported that
candles created concentrations of air pollution that
are unsafe. But the journalist did not provide any
data to back up the claim. Because Weber lived next
door to a church, he decided to look into the issue
himself.
