README
This directory contains output data from the BU Monte Carlo model used in:

"Temporal Variability Largely Explains Difference in Top-down and Bottom-up Estimates of Regional-Scale Methane Emissions" 
Vaughn, T.L., et al. 2017

in plain text, tab delimited format.

'/TimeSeries' contains three text files:
Mean.txt
Lower95CI.txt
Upper95CI.txt

Each of these files contains hourly methane emission rates for all source categories and sub-categories included in the BU model in megagrams of methane per hour (Mg/h CH4), except for columns "ProductionMLUCount" and
"ProductionMLUDurationHrs" which contain counts and durations for manual liquid unloadings (MLUs) in the production sector.

Each row lists emission rates for modeled sources categories and sub-categories for the 48 hour study period spanning October 1st and 2nd, 2015.
Hour 0 corresponds to 00:00 CDT on October 1st, 2015.
Mean.txt lists the mean of the emission rate distribution developed in the Monte Carlo model for given source categories.
Lower95CI.txt lists the lower bound of the 95% confidence interval of the emission rate distribution developed in the Monte Carlo model for given source categories, i.e. the 2.5th percentile of cumulative source category emissions.
Upper95CI.txt lists the upper bound of the 95% confidence interval of the emission rate distribution developed in the Monte Carlo model for given source categories, i.e. the 97.5th percentile of cumulative source category emissions.

'/Oct1' and '/Oct2' ('/OctX' hereafter) each contain spatiotemporal methane emission rate data for modeled source categories in two sub-directories:
'/OctX/DownwindMgPerHrPerDegLong' contains simulated downwind longitudinal emission rate profiles in megagrams of methane per hour per degree longitude (Mg/h/deg CH4) for modeled source categories.
'/OctX/GridCellCentroidMgPerHr' contains BU model results by grid cell in megagrams of methane per hour (Mg/h CH4) for modeled source categories and sub-categories. The location given is the centroid of the BU model grid cell.
One text file is included for each hour of the 48 hour study period spanning October 1st and 2nd, 2015. 

'/OctX/DownwindMgPerHrPerDegLong'
also includes subtotals for the production sector in:
'/ProductionSubtotalExcMLU' - methane emissions from the production sector excluding those from manual liquid unloadings (MLUs)
'/ProductionSubtotalMLU' - methane emissions from manual liquid unloadings (MLUs)

'/OctX/GridCellCentroidMgPerHr'
The files contain no headers; they are described below with sample data from the file.

* FacilityCountInGridCell included only for ProductionTotal (Wellpad Count), GatheringTotal, and TransmissionTotal. Emissions in from gridcells in GatheringTotal with zero facility count are from gathering pipelines.

also includes counts and durations for manual liquid unloadings (MLUs) in:
'/ProductionMLUCount'
'/ProductionMLUDurationHrs'
