title: Colorado Ongoing Basin Emissions Study (COBE) anonymized final data set of emissions measurements

description: This dataset contains anonymized emissions measurements collected by
 aerial vendors across multiple campaigns for the Colorado Ongoing Basins
 Emission (COBE) study. The data has been processed to ensure
 confidentiality for site operators, while retaining as much metadata as
 possible necessary for analysis and modeling replications. Facility names
 and locations have been removed and replaced with an anonymized facility
 identifier. This way, emissions from similar facilities share a unique
 identifier. Maintenance emissions (which are treated differently when
 developing a predictive model) are included, while emissions that are
 determined to be from non-production sites are not. Measurements that do
 not align with reported oil/gas facilities are also excluded from this
 file.
description: This COBE_Anonymized_emissions.csv file contains anonymized emissions
 measurements collected by aerial vendors across multiple campaigns for the
 Colorado Ongoing Basins Emission (COBE) study. The data has been processed
 to ensure confidentiality for site operators, while retaining as much
 metadata as possible necessary for analysis and modeling replications.
 Facility names and locations have been removed and replaced with an
 anonymized facility identifier. This way, emissions from similar
 facilities share a unique identifier. Maintenance emissions (which are
 treated differently when developing a predictive model) are included,
 while emissions that are determined to be from non-production sites are
 not. Measurements that do not align with reported oil/gas facilities are
 also excluded from this file. Important fields: * Anonymized_Facility_ID:
 8-character identifier generated using a hash function * Season: Flight
 campaigns are grouped by season of Summer, Spring, Fall, Winter, or blank.
 Blank values indicate that the data is taken from another study with
 different flight timing then those done specifically for COBE. * Basin:
 Geographic basin in which the measurement was taken. For the COBE study,
 oil/gas basins were grouped into three categories, Denver-Julesberg (DJ)
 basin, Piceance basin, and 'other', which includes everywhere
 else in Colorado. * Equipment type: For Bridger, this reflects the
 equipment type reported in their dataset. For GHGSat and Insight M, the
 equipment type is listed as unknown unless it was specified by the
 operator. * Emission rate (kg/h): Observed emission rate by aerial
 measurement, rounded to two decimal points. * Emission rate (upper &
 lower) 95CI: 95% confidence interval bounds, both upper and lower. * PS:
 Prototypical Site, classification assigned to facilities of different
 configurations (see COBE report main text) * Aircraft company: Vendor of
 aerial instrument product used to record measurement. * Sensor: Specific
 sensor product/technology used to detect emission * Partner? (Y/N):
 Indicates whether facility operators participated in the COBE study. When
 'Yes', some insight into the cause analysis process should be
 available. * Type of Emission: Emissions are classified into four
 categories for the modeling in this study: Normal Operations, Maintenance,
 and Fugitive/leak, and emissions with unclear or not classified causes are
 denoted 'Other' or 'Unknown'. * Cause: Where
 information from participating operators is available, this column
 provides the likely determined cause of emission. --- This dataset is
