GLOBALVIEW data products consist of several hundred text files. Encoded in each file name is
the sampling location, platform, and strategy, contributing laboratory, file content, and gas
identifier. All file names use the following naming scheme:
[site][data grouping]_[lab#][strategy][platform]_[qualifier].[gas]
- [Sampling Site]
(ex) brw_, poc_, car_, amt_
- [Data Grouping]
Data may be grouped by date, latitude, longitude, altitude, etc.
If data are grouped by date then identifier has yyyy[mm][dd] format.
(ex) brw2005_, amt200403_, lef20050315_
If the sampling platform is an aircraft then the identifier is a
3-character numeric field with units of 102 meters (hm) above sea level.
(ex) car040_, haa005_
If the sampling platform is a ship then the identifier is a 3-character
alphanumeric field with units of degrees (00-90). Bins in the northern
and southern hemispheres are denoted as n## and s## respectively. The
equatorial bin is denoted as 000.
(ex) pocs25_, poc000_, scsn03_
- [Measurement Laboratory ID Number]
A two character numeric field identifies the measurement laboratory (01-99).
NOAA ESRL is lab number 01 (link?).
(ex) pocs25_01, alt_06, aia_02D2
- [Sampling Strategy]
A single alphanumeric character (0-9,a-z,A-Z) indicates the sampling strategy.
_??C | Quasi-continuous |
_??D | Discrete |
(ex) pocs25_01D, alt_06C, aia_02D
- [Sampling Platform]
A single alphanumeric character (0-9,a-z,A-Z) indicates the sampling platform.
_???0 | Single Fixed Surface Site |
_???1 | Ship |
_???2 | Aircraft |
_???3 | Tower |
(ex) sis_02D0, pocs25_01D1, frd040_06C3, aia005_02D2
- [File Content Qualifier]
An alphanumeric string describes the type of data included in the file.
_????_ext | Extended Record |
_????_wts | Extension Weights |
_????_var | Atmospheric Variability Statistics |
_????_seas | Seasonal Pattern Statistics |
_????_diu | Diurnal Pattern Statistics |
_????_tod | Sampling Time-of-Day Statistics |
_????_mtx | MBL Reference Matrix |
(ex) sis_02D0_ext, pocs25_01D1_tod, frd040_06C3_diu, ref_mbl_mtx
- [Gas Name]
Identifies the trace gas species.
_????_???.co2 | Carbon Dioxide |
_????_???.ch4 | Methane |
_????_???.co | Carbon Monoxide |
_????_???.co2c13 | δ13C (CO2) |
(ex) sis_02D0_ext.co2, pocs25_01D1_tod.co2c13, frd040_06C3_diu.ch4, ref_mbl_mtx.co
