GLOSSARY

 

ASCII ‑‑ American Standard Code for Information Interchange, a standard set of codes used by computers and communication devices.  Sometimes used to refer to files containing only such standard codes, without any application‑specific codes such as might be present in a document file from a word processor program.

 

CD‑144 Format ‑‑ Card Deck‑144 data format available from NCDC for National Weather Service surface observations commonly used for dispersion models.  Each record represents an 80‑column "card image".

 

CO ‑‑ COntrol, the 2‑character pathway ID for input runstream images used to specify overall job control options.

 

CO Pathway ‑‑ Collective term for the group of input runstream images used to specify the overall job control options, including titles, dispersion options, terrain options, etc.

 

Directory ‑‑ A logical subdivision of a disk used to organize files stored on a disk.

 

Dispersion Model ‑‑ A group of related mathematical algorithms used to estimate (model) the dispersion of pollutants in the atmosphere due to transport by the mean (average) wind and small scale turbulence.

 

DOS ‑‑ Disk Operating System.  Software that manages applications software and provides an interface between applications and the system hardware components, such as the disk drive, terminal, and keyboard.

 

EBCDIC ‑‑ Extended Binary Coded Decimal Interchange Code, the collating sequence used on IBM mainframe computers.

 

Echo of inputs ‑‑ By default, the ISC models will echo the input runstream images, character by character, into the main printed output file.  This serves as a record of the inputs as originally entered by the user, without any rounding of the numerical values.  The echoing can be suppressed with the NO ECHO option.

 

EOF ‑‑ End‑of‑File.

 

EPA ‑‑ U. S. Environmental Protection Agency.

 

Error message ‑‑ A message written by the model to the error/message file whenever an error is encountered that will inhibit data processing.
