3.3.2.3 Comments

       The India Meteorological Department (IMD) records the data at two times a day viz.
       0830 hr and 1730 hr while the site specific data has been recorded at an hourly
       interval. On comparison of site specific data generated for study period vis-à-vis the
       IMD data, slight variations were found. The following observations are brought out:

       •   The temperature recorded on site when compared vis-à-vis the IMD data, slight
           variations were found. The maximum and minimum temperatures recorded at
           site during study period were 42.0oC and 21.3 oC, whereas the maximum and
           minimum temperature recorded at IMD, Raigarh for the same season are 42.6oC
           and 20.3oC respectively;

       •   The relative humidity was observed to range from 20.3% to 41.3% during the
           study period whereas according to IMD Raigarh data the relative humidity was
           observed to range from 20.4% to 41%. The variation could be because of the
           fact that the RH values considered for the site are actual values while the range
           of IMD, Raigarh data represents the average values for 30 year period.

       The data generated at continuous monitoring station at project site when compared
       with the data recorded at IMD, it can be observed that the data generated at the
       site is broadly compatible with regional meteorology, except minor variations as
       descried above.
