A simple method to minimize orientation effects in a profiling radiometer
Suresh, T.; Talaulikar, M.; Desa, E.; Matondkar, S.G.P.; SrinivasaKumar, T.; Lotlikar, A. (Taylor & Francis, 2012)Marine optical parameters required for ocean color satellite applications must be measured with high accuracy and errors within the permissible limits. These stringent requirements demand careful measurements of optical ... -
Comparison of measured and satellite-derived spectral diffuse attenuation coefficients for the Arabian Sea
Suresh, T.; Talaulikar, M.; Desa, E.; Matondkar, S.G.P.; Mascarenhas, A. (Taylor & Francis, 2012)The results of study comparing the spectral diffuse attenuation coefficients Kd(Lambda) measured in the Arabian Sea with those derived from the Sea-Viewing Wide Field-of-View Sensor (SeaWiFS) using three algorithms, of ... -
Empirical algorithm to estimate the average cosine of underwater light field at 490 nm
Talaulikar, M.; Suresh, T.; Desa, E.; Matondkar, S.G.P.; Kumar, T.S.; Lotliker, A.; Inamdar, A. (Taylor & Francis, 2012)The average cosine of the underwater light field mu(lambda), where lambda is the wavelength, is an apparent optical property (AOP) that describes the angular distribution of radiance at a given point in water. Here, we ... -
Evaluation of methods to determine the spectral variations of aerosol optical thickness
Suresh, T.; Talaulikar, M.; Rodrigues, A.; Desa, E.; Chauhan, P. (Indian Aerosol Science and Technology Association, 2007)The methods used to derive spectral variations of aerosol optical thickness, AOT are evaluated. For our analysis we have used the AOT measured using a hand held sunphotometer at the coastal station on the west coast of ... -
Evaluation of satellite derived spectral diffuse attenuation coefficients
Suresh, T.; Talaulikar, M.; Desa, E.; Mascarenhas, A.A.M.Q.; Matondkar, S.G.P. (National Institute of Technology, Surathkal, 2007)Spectral diffuse attenuation K sub(d)(lambda) is an important apparent optical property that provide information about the attenuation of the spectral downwelling solar irradiance with depth in water. The spectral K ... -
