Description 88-95
There are various sources of errors from
the measurements of optical parameters using a radiometer, which can be classified
as mode of deployment, instrument and environment. The errors from the
deployment are primarily from the ship and superstructure shadows. Instrument
could be a source of error arising from its self-shadow, drift in the calibration
and temperature effects. There could be large errors, which at times may be
unavoidable to environment factors such as wave focusing at the surface layers,
sea state conditions which may affect the tilt of the instrument, atmospheric
conditions such as cloud cover, solar elevation, wind and rain. Radiometric
optical data in water could also get affected due to Raman scattering and
fluorescence effects. Here we discuss the above sources of errors and how they could
be minimized. From the measurements carried out in the coastal waters off Goa
and Arabian Sea using the hypespectral radiometer,
we propose simple protocol to measure the data and also screen the erroneous
data measured from the radiometer.
