Field Param eter Description Explanation
1 Num ber of Instrum ents num eric value of num ber of
instrum ents supplying data m ore than one instrument m ay be supplying
the transm ission data
2 Instrum ent #1 Type num eric key defining type of
instrument direct pointing (1), cosine derived (2)
3 Instrum ent Description Text description of instrum ent Manufacturer, model, serial num ber (if
applicable), general inform ation on method
of observation, data collection, etc.
4 Detector Type Text description of the detector The type of detector (e.g., photodiode,
PMT, single, array). The manufacturer and
m odel of detector used (if known). If m ore
than one type of detector is used indicate
the detector/wavelength pairing
5 Optics Type Text description of the instrument
optical train. Description of optics (e.g., single detector
with filter wheel; m ultiple detectors with
m ultiple entrance apertures; focussed
system ; grating; prism ; etc.)
6 Field of View
Param eters Num eric parameters based on
type of optics Inform ation such as opening angle, slope
angle, f-num ber for focussing instrum ents,
directional responsivity for cosine-type
instrum ents, etc.
7 Num ber of
wavelengths Num eric value of the num ber of
wavelengths Multiple wavelengths are possible from
each instrument
8 Calibration method Num eric key indicating type of
calibration Langley (1), Instrum ent com parison (2),
standard lam p (3), trap detector (4),
com bination or other (5)
9 Calibration description Text description of calibration
m ethod Detailed inform ation on method of
calibration
10 Calibration date Date of calibration. Date to be
given in same form at as
broadband calibrations. The calibration date given m ay not be the
m ost recent calibration.
11 W avelength #1 Actual wavelength (8) The measured central wavelength of the
passband (e.g., 501.2 nm , not 500 nm )
12 Bandpass #1 W idth of first bandpass (*8) Measured FW HM of bandpass
13 Description of
bandpass #1 Text description of bandpass Inform ation on filter function, blocking filters,
slit function etc., depending on type of
instrument
14 Calibration uncertainty
for wavelength #1 Num eric parameters that describe
the uncertainty of the calibration
procedure Include the com bined uncertainty of all
aspects of the calibration and the
confidence level
15 Repeat fields 11 - 14
for each w avelength
16 Repeat fields 2 - 15
for each instrum ent
