Aerminute user guide

A Multi User license allows for unlimited installations of this program on computers at a single address. With the downloaded meteorological data, you can call and run AERMET and AERMINUTE to process raw data into an AERMOD-ready format. With the ambient monitoring data, AERMOD Wizard can create an AERMOD-ready background data file that can The AERMET user's guide defines spring as the 1-2 months after the last killing frost.

On October 8, 2015, the U.S. EPA published an update to the AERMINUTE ASOS wind data preprocessor on the SCRAM website.AERMINUTE Version 15272 includes the ability to read 5-minute ASOS data files. Lakes Environmental will incorporate the new AERMINUTE in the next release of AERMET View.Users in current maintenance will be able to download this update from Lakes Environmental's Software AERMINUTE 15272 f Imports AERSURFACE files directly, making compliance with standard U.S. EPA land-use practices easy f Choose between letting AERMET calculate land use for you or manually inputting land use values into the redesigned Land Use interface, helpful for international users and U.S. users with state-specific land use requirements The new AERMINUTE includes Source Code, Executable, and User's Guide. AERMINUTE processes 1-minute ASOS wind data to generate hourly wind speed and wind directions to supplement data within standard hourly ASOS data. The U. S. EPA issued a Clarification Memorandum titled: "AERSCREEN Released as the EPA Recommended Screening Model". (see Appendix B of the AERMET User's Guide) In addition, for the 8773 hourly obs, AERMET reports that there are: 2075 CALM WIND CONDITIONS (WS=0, WD=0) 0 ZERO WIND SPEEDS WITH NONZERO WIND DIRECTIONS 0 DEW-POINT GREATER THAN DRY BULB TEMPERATURES The date & time of these occurrences can be found in the message file MCR_ST1.MSG MCR_ST1.RPT A minimum of 54 (total) 1-min measurements were required to produce an hourly record. This process yielded between 60 000 and 67 000 hourly records at all but one site, representing 86%-96% of all possible reporting hours ( Table 1 ). The exception was Lander, Wyoming, with 58 536 hourly records (83.5% of possible reporting hours). b. Introduction. Aircraft engine exhaust emissions are a significant source of ultrafine particles (UFP; aerodynamic diameter <100 nm) and can cause several-fold increases in ground-level particle number concentrations (PNC) over large areas downwind of airports. 1−4 The spatial extent and magnitude of the impact varies depending on factors including wind direction and speed, runway use pattern Introduction This document serves as a technical discussion of the methodology used to process the 2015-2019 meteorological data for AERMOD. It focuses on those portions of the process that are not described in the AERMET user guide, or where the instructions in the AERMET user guide were expanded upon. AERMINUTE generates hourly averaged wind speed and wind direction to supplement
