Spectral response function#
A spectral response function data set provide the spectral response of a given instrument on a specific platform and in a specific spectral band.
Data access#
All spectral response function data sets required by Eradiate are managed the data store (see Introduction for details).
Identifier format#
Identifiers for spectral response function are built according to the format
{platform}-{instrument}-{band}.nc
where:
platform
identifies the platform (e.g. satellite’s name),instrument
identifies the instrument onboard the platform,band
specifies the spectral band of the instrument that is being characterised.
For example, the spectral response function data set of the SLSTR instrument
onboard Sentinel-3B and in the spectral band number 5 has the identifier
sentinel_3b-slstr-5
.
Structure#
Spectral response function data sets include two data variables:
the instrument’s spectral response function (
srf
),the uncertainties on the
srf
data (srf_u
),
and one dimension coordinate:
the wavelength (
w
).
Both data variables (srf
and srf_u
) are tabulated against the
wavelength.
The following additional data set attributes are provided:
platform
: platform identifier (e.g.sentinel_3b
),instrument
: instrument identifier (e.g.slstr
),band
: spectral band number (e.g.5
).
