3. AERMET
INPUT:
1. Upper air data: format: FSL, source: https://esrl.noaa.gov/raobs, station identifier: 54775
(WBAN), time: May 01, 2011 to April 30, 2012. (The time is different for case-ii)
2. Surface met data: source: source: ftp://ftp3.ncdc.noaa.gov/pub/data/noaa, specimen file
name: 14737-YYYY.dat, concatenate files of 2011 and 2012.

OUTPUT:
1. mc_2011-12.sfc – Boundary layer parameters, an input for AERMOD.
2. mc_2011-12.pfl – Profile of atmospheric variables, an input for AERMOD.
AERMET is processed in three stages. Stage-1 extracts the achieved data and generates quality-
assured data. Stage-2 combines the three files - upper air, surface parameters and onsite data –
in one day blocks. Stage-3 performs calculations and output results for AERMOD.
STAGE-1
INPUT:
1. 54775-2011-2012.fsl – Upper air data, concatenated from 2011-2012.
2. 14737-2011-2012.dat – Surface wind data, concatenated from 2011-2012.
3. data mcospfl_11-12.dat – Site specific data (??), site observations.
OUTPUT:
1. alb_2011-12.oqa – Upper air data, an input for Stage-2.
2. 14737_2011-12.oqa – Surface wind data, an input for Stage-2.
