Quality of temperature and salinity data from Argo profiling floats in the Bay of Bengal

In the present study, temperature and salinity from APEX -Argo floats with reported SPB (Argo-SPB) and salinity from normal floats without any reported SPB (Argo-N) in the BoB have been subjected to quality check (QC). Method used for QC depends on time-space de-correlation scales (TSD-scales) of temperature and salinity in the BoB at selected potential temperature ( surface (10 C). High quality shipboard CTD observations in the BoB have been used to identify TSDscales of temperature and salinity. Observed TSD scales for salinity (temperature) at  surface of 10 C are 5 days and 60 km (8 days and 80 km). QC has been performed on matchups between Argo and shipboard CTD observations falling within the identified TSDscales. QC on Argo-SPB could not identify any significant systematic bias/error, except for a single profile (cycle No. 48) of float-4900675. In the case of Argo-N, significant error is found in most of the salinity profiles from the float-2900268.
