co2-ppm-daily's Issues

Improve documentation

  • The README is just inaccurate (e.g. preparation section!)
  • Data section should explain where data came from and why we have two different data sources
    • I would also have a short comment in the python script about this too ...
  • Description at top should be a paragraph
  • Should not be a heading at the top of the readme
  • Details of source data structure and what we extract (e.g. summary like below and then explain what we extract)
# site_code:long_name : site_name_abbreviation.
# site_code:comment : Site code is an abbreviation for the sampling site name.
# time_components:_FillValue : -9
# time_components:long_name : integer_components_of_UTC_date/time
# time_components:order : year, month, day, hour, minute, second
# time_components:comment : Calendar time components as integers.  Times and dates are UTC. Time-averaged values are reported at the beginning of the averaging interval.
# value:_FillValue : -999.999
# value:long_name : measured_mole_fraction_of_trace_gas_in_dry_air
# value:units : micromol mol-1
# value:comment : Mole fraction reported in units of micromol mol-1 (10-6 mol per mol of dry air); equivalent to ppm (parts per million).
# value_std_dev:_FillValue : -99.99
# value_std_dev:long_name : standard_deviation_in_reported_value
# value_std_dev:units : micromol mol-1
# value_std_dev:comment : This is the standard deviation of the reported mean value when nvalue is greater than 1. See provider_comment if available.
# nvalue:_FillValue : -9
# nvalue:long_name : number_of_measurements_contributing_to_reported_value
# nvalue:comment : Number of individual measurements used to compute reported value. See provider_comment if available.
# latitude:_FillValue : -999.999
# latitude:standard_name : latitude
# latitude:long_name : sample_latitude_in_decimal_degrees
# latitude:units : degrees_north
# latitude:comment : Latitude at which air sample was collected.
# longitude:_FillValue : -999.999
# longitude:standard_name : longitude
# longitude:long_name : sample_longitude_in_decimal_degrees
# longitude:units : degrees_east
# longitude:comment : Longitude at which air sample was collected using a range of -180 degrees to +180 degrees.
# altitude:_FillValue : -999.999
# altitude:standard_name : altitude
# altitude:long_name : sample_altitude_in_meters_above_sea_level
# altitude:units : m
# altitude:comment : Altitude (in meters above sea level). See provider_comment if available.
# altitude:provider_comment : Altitude for this dataset is the sum of surface elevation (masl) and sample intake height (magl).
# elevation:_FillValue : -999.999
# elevation:standard_name : elevation
# elevation:long_name : surface_elevation_in_meters_above_sea_level
# elevation:units : m
# elevation:comment : Surface elevation in meters above sea level. See provider_comment if available.
# intake_height:_FillValue : -999.999
# intake_height:long_name : sample_intake_height_in_meters_above_ground_level
# intake_height:units : m
# intake_height:comment : Sample intake height in meters above ground level (magl). See provider_comment if available.
# qcflag:_FillValue : NA
# qcflag:long_name : quality_control_flag
# qcflag:comment : This quality control flag is provided by the contributing PIs. See provider_comment if available.
# qcflag:provider_comment : This is the NOAA 3-character quality control flag.  Column 1 is the REJECTION flag. An alphanumeric other than a period (.) in the FIRST column indicates a sample with obvious problems during collection or analysis. This measurement should not be interpreted. Column 2 is the SELECTION flag. An alphanumeric other than a period (.) in the SECOND column indicates a sample that is likely valid but does not meet selection criteria determined by the goals of a particular investigation. Column 3 is the INFORMATION flag. An alphanumeric other than a period (.) in the THIRD column provides additional information about the collection or analysis of the sample.

Full version of the dataset

Extract everything including the metadata - both field metadata and summary into a full data package so that we can show what this would look like and someone can get the full version if they want.
