Abstract:

The partial pressure of carbon dioxide (pCO2) is one of the most effective measurements of carbon dioxide in seawater, and the increases in pCO2 profoundly affect the marine carbonate system. The role of SST on pCO2 is analyzed to develop a regional pCO2 algorithm using in-situ SST and calculated pCO2 by employing the polynomial regression functions such as linear, quadratic, and cubic to develop a pCO2 map and the best-fit algorithm of the cubic function developed for the postmonsoon season with an R2 of 0.537 and SEE of ± 36.543 has been validated for remote sensing applications. Evaluation of satellite-derived pCO2 with calculated pCO2 showed R2 of 0.498 and the root means square error (RMSE) of ±30.922 µatm with 75% of overestimation of calculated pCO2 by the satellite-derived pCO2. The satellite-derived pCO2 map error is mainly because of the inbound errors in MODIS-derived SST products. Hence, improvement in sensor technology and retrieval algorithm would improve the retrieval of input parameters (SST), which is useful in estimating pCO2 precisely. This would enable us to understand the biogeochemical processes behind the variability of CO2 in the surface waters of the southwest Bay of Bengal.
