Remote Sensing of Leaf Area Index and Primary Productivity

By Prof. MD Behera   |   IIT Kharagpur
Learners enrolled: 814
The leaf area index (LAI) is a response parameter for photosynthesis as it directly relates to the light interception and gas exchange through the stomata. It is a dimensionless biophysical variable, which is calculated as the ratio of leaf area to per unit ground surface area. Monitoring of the LAI provides an understanding of dynamic changes in productivity, climate impacts on terrestrial ecosystems, energy balance, canopy water interception, and gas exchange. Therefore, understanding of the LAI is a crucial parameter for physiological, ecological, and climatological studies.

Instructor bio

Prof. MD Behera

IIT Kharagpur
Dr. MD Behera has made outstanding contributions to the fields of forest remote sensing and ecological climatology through theorizing, modeling and conducting innovative experiments and field-based measurements. He has developed innovative protocols and new methods for estimating a range of vegetation photosynthetic/ structural variables including leaf area index, canopy height, canopy chlorophyll, aboveground biomass and productivity using suite of satellite data products and modeling.

Course certificate

The course is free to enroll and learn from. But if you want a certificate, you have to register and write the proctored exam conducted by us in person at any of the designated exam centres.
The exam is optional for a fee of Rs 1000/- (Rupees one thousand only).

Registration url: Announcements will be made when the registration form is open for registrations.
The online registration form has to be filled and the certification exam fee needs to be paid. More details will be made available when the exam registration form is published. If there are any changes, it will be mentioned then.
Please check the form for more details on the cities where the exams will be held, the conditions you agree to when you fill the form etc.


Average assignment score = 25% of average of best 3 assignments out of the total 4 assignments given in the course.
Exam score = 75% of the proctored certification exam score out of 100

Final score = Average assignment score + Exam score

YOU WILL BE ELIGIBLE FOR A CERTIFICATE ONLY IF AVERAGE ASSIGNMENT SCORE >=10/25 AND EXAM SCORE >= 30/75. If one of the 2 criteria is not met, you will not get the certificate even if the Final score >= 40/100.

Certificate will have your name, photograph and the score in the final exam with the breakup.It will have the logos of NPTEL and IIT Kharagpur .It will be e-verifiable at nptel.ac.in/noc.

Only the e-certificate will be made available. Hard copies will not be dispatched.

Once again, thanks for your interest in our online courses and certification. Happy learning.
