- General Information
Two different versions of TRIM.ExpoInhalation (also known as APEX) are available: APEX 3.3 for use within TRIM, and APEX 4.02, for stand alone use. For information about and documentation on these releases of TRIM.Expo Inhalation / APEX, please see the TRIM.Expo Inhalation / APEX page. For information on new files, models, etc., please click on "Recent Additions" link at top of page left of the "Search" box.
- Installation Instructions
User’s may install and run TRIM.Expo in “stand alone” mode, or within the TRIM MIMS framework. If running TRIM.Expo within the TRIM MIMS framework, the TRIM installation program will install APEX3.3, which is the version currently compatible with TRIM. If running TRIM.Expo in the “stand alone” mode, follow the instructions below for installing APEX 4.02.To take advantage of the features associated with running TRIM.Expo (as APEX3.3) as a TRIM “project”, use the TRIM installation program to install required components. The TRIM.Risk User’s Guide, Volume I describes how to run TRIM projects. Volume II describes the use of TRIM.Expo with TRIM.Risk. Example TRIM projects using HAPEM are also available.
Instructions for installing TRIM.Expo in “stand alone” mode follow:
Download any documentation files of interest from the TRIM.Expo Inhalation / APEX page .
-
Download the APEX 4.02 executable zip file. (see Section 3, Software Available for Download)
Select a directory in which you wish to install APEX (e.g. C:\models\apex ) and unzip the executable into that directory. This directory will be referred to as the "Default Directory".
-
Download the Input Files and unzip them into the Default Directory.
[Optional] Download the sample output files and unzip them into any directory. Note: if you install them under the Default Directory, they will be overwritten when you execute APEX.
- Software Available for Download
See FERA recent additions for information on updates to TRIM.Expo and associated programs. Please read installation instructions before installing files.
- TRIM.Expo (using APEX3.3) may be downloaded and installed using the TRIM Installation program.
- APEX 4.02 for Windows (1.2 MB executable) (8/15/2007)
- Input Files
Please read installation instructions before installing files.
For TRIM.Expo/APEX4 in the “stand alone” mode, the required versions of national files listed below are included in this single package, APEX 4.02 Input Files (78 MB zipped).
For TRIM.Expo within the MIMS framework, the following national databases are required (in addition to what is installed via the TRIM Installation Program in Section 2).
A. National Databases. These national databases can be used with any version of APEX for most applications in the U.S. The user also has the option to use alternative databases (e.g., if the user wishes to model a subpopulation). Examples of the other input files, which are prepared by the user, can be found in the Section 5, Example Applications, below. The three databases below should be installed into subdirectories to the APEX directory specified during TRIM installation (see section 2.1, step 5.a. of the Installation Instructions for TRIM).
-
Consolidated Human Activity Database (CHAD) and other human characteristics data files (4 MB zipped) (activity diaries, metabolic and physiological parameters) (3/1/2005)
-
Population Files (32 MB zipped) (2000 tract-level Census counts, tract locations, employment probabilities by age and tract) (4/30/2003)
-
Commuting Database (40 MB zipped) (Adult commuting patterns based on the 2000 Census) (8/29/2005)
B. Utility Programs. Posted below are utility programs for users with particular applications (e.g. use of ISCST outputs or need for census block level results).
- ISCAPEX (216 KB zipped) (2/16/2004) is a DOS-based utility that reformats ISCST3 results into the format
required by APEX for air quality
files and creates the districts input file required by APEX (all versions).
- APEX Block File Builder (384
MB zipped) (8/15/2005) is
a DOS-based utility that creates block-level input data files for all versions of APEX for
user-specified
locations (i.e. counties). The APEX input files created by the utility
for the selected locations are: sector location file (block
FIPS codes; latitude
and longitude of each block centroid); employment file (block
FIPS codes; employment probability by gender and age group for each block); population
files (one file for each gender; block FIPS codes; population by
age bin for each block); and commuting file (each block FIPS
code and cumulative fractions
of population commuting to work blocks). Included in this zip file is a user's
guide for this utility.

- Example Applications
- 12 Cities Ozone Modeling 2002 Base Case Input Files (6 MB zipped) (8/15/2007) - These files include the TRIM.Expo (APEX 4.02) inputs for the 2002 base case exposure modeling conducted in support of the current review of the ozone NAAQS, except for the national population and commuting databases (see Input Files, above).
- 12 Cities Ozone Modeling 2002 Base Case Output Files (<1 MB zipped) (8/15/2007) - These files include the output files for the 2002 base case exposure modeling conducted in support of the current review of the ozone NAAQS.
- 12 Cities Ozone Modeling Input Files - Other Scenarios (36 MB zipped) (8/15/2007) - These files include the additional TRIM.Expo (APEX 4.02) inputs for the other scenarios modeled in support of the current review of the ozone NAAQS.
- 12 Cities Ozone Modeling Output Files - Other Scenarios (6 MB zipped) (8/15/2007) - These files include the output files for the other scenarios modeled in support of the current review of the ozone NAAQS.
- TRIM.Expo (1 run) Example Application - The first zip file package in
step 2 below provides instructions for setting up and running an example
application where TRIM.ExpoInhalation
(i.e., APEX3) calculates inhalation exposure estimates for a single chemical,
study area, facility, and source.
- TRIM.Expo (>1 run) Example Application – The second zip file package below provides instructions for setting up and running an example application where TRIM.ExpoInhalation (i.e., APEX3) calculates inhalation exposure estimates for multiple combinations of chemical, study area, facility, and sources.
- TRIM.Expo (1 run) Example Application (217 MB zipped) (12/13/2005). This zip file contains 27 files.
- TRIM.Expo (>1 run) Example Application (94 MB zipped) (12/28/2005). This zip file contains 29 files.

B. Air Toxics – Note, these applications are for training purposes only and are not intended to apply to any real world situation
Step 1. If TRIM has not been previously installed, install it using the TRIM Installer. Be sure to select "Inhalation Exposure Assessment with TRIM.Expo" when prompted to "Please select the activities you expect to perform with TRIM."
Step 2. Download the ZIP file for the desired example application:
Step 3. Unzip the zip file from previous step into the "input" subdirectory of your APEX directory (e.g., C:\Models\APEX\input). Be sure to maintain the directory structure of the files being unzipped. This is done by default with WinZip's Wizard interface, and is done by checking the "Use folder names" box in the Extract screen of WinZip's Classic interface.
Step 4. Print the “StepsForTRIM…” pdf file (unzipped in Step 3) and follow its steps.
