TCCON Spectrum Naming Convention

The TCCON spectra have a 20-character naming convention that is detailed below. This philosophy underlying this is to
1) Avoid spectra from different sites having the same name
2) Accomodate a single instrument operating from various different sites
3) Accomodate multiple instruments at a single site (e.g. intercomparisons)
4) Encode into the spectrum name information that is missing from the OPUS header (e.g. site, external source, presence of an internal cell, presence of a dichroic or filter).

Spectrum naming convention (revised 2008-12-03)

Characters Denotes Explanation

1 Site (See two-letter identifiers table below.)

2 Instrument (See two-letter identifiers table below.)

3-6 Year 2007, 2008, etc (4 digit)

7-8 Month 01=January, 02=February, etc.

9-10 Day 01, 02, ....31

11 Source s=sun, m=moon, l=lamp, a=scattered sky

12 Internal Cell 0=None, (a-f)=10 cm TCCON HCl, g= additional 10cm HCl, h=5 cm NDACC HBr, i=20 cm N2O

13 Beamsplitter a=Caltech CaF2, b=Lauder CaF2, c=Darwin CaF2, d=Lamont CaF2, e=other

14 Dichroic 0=None, a=Caltech, b=Lauder, c=Darwin, d=Lamont, e=other

15 Optical Filter 0=None, a=Red Glass, b=Ge, etc

16 Detector a=InGaAs, b=Si, c=InSb, etc., x=both 'a' and 'b' channels

17 "." Period

18-20 Extension 001-999

18-21 Extension 0001-9999

^* 3 and 4 digit extensions both acceptable.
