Session : 1 Remote sensing application in marine pollution/waterquality handled by Dr Sisir Kumar Dash - Scientist E - National Centre for Coastal Research , Ministry of Earthsciences -Government of India
Highlights of the Session - I
• The role of NCCR in shoreline management, marine spatial planning, marine pollution studies, ecosystem-based services and capacity building were highlighted.
• The mandate for NCCR to detect periodical changes in coastal water quality, predict pollution levels and determination of sea water quality criteria, quantification od marine litter and micro plastics for actions to ensure the protection of marine environment were elaborated.
• The importance of water quality and about Seawater Quality Monitoring Program and how it supported the National indicator Framework of Sustainable Development Goal (SDG)-14 was informed.
• The physico-chemical parameters along the west coast of India and about the importance of coastal water quality index (CWQI) on determining water quality of a region was discussed in detailed and also briefed how remote sensing helps in estimating water quality parameters with many examples.
• The role of Machine learning and Artificial intelligence in data assimilation, data fusion and development of algorithms and the importance of remote sensing of ocean colour data, its uses and how to choose a satellite data for remote sensing for retrieving water quality was addressed with the importance of spectral signatures and parameter retrieval mechanism using it.
• The retrieval of chlorophyll using a satellite data with examples and the procedures involved in the process were touched with short introduction to the different functional and empirical algorithms.
• How algal blooms leads to pollution and about the algorithms used for estimating bloom index. The hazards due to plastics in ocean and how marine litter was analysed quantitatively using digital data from space borne observations and about the barriers in building spectral signatures of plastics are demonstrated with case reports.
• Encouraged the participants to carry on research works regarding this.
Session : 2 Thermal remote sensing applications in environmental assessment handled by Dr Eswar Rajasekaran - IIT Bombay
Highlights of the Session - II
• The fundamentals, energy transfer mechanisms and the basic laws used for Thermal Infra-red remote sensing was highlighted.
• The process of atmospheric correction, radiative transfer models (RTM) and also about emissivity were conveyed
• Diurnal LST cycle, data fusion algorithms and disaggregation models and its application were detailed.
• The process of Evapotranspiration and the factors like sensible heat flux, latent heat and ground heat flux involved were expressed to the participants.
• Mapping ET and about drought monitoring from ET, urban heat island with the example of ECOSTRESS LST sensor was addressed in his lecture.
• The applications of TIR data like, Earth quake prediction from thermal anomalies, disease carrier modelling using vector modelling and mining were elaborated with examples.
