| dc.description | Fog is the most common weather hazard during winter period (December-January) over the Indo-
Gangetic plain due to favorable meteorological conditions. It causes a number of health hazards and also leads to economic losses. It affects the transportation and it has been reported that every year almost over 38,700 vehicle crashes occur in during fog period [1]. Fog formation occurs when water vapours present in the air forms water droplets. These water droplets get suspended in the air, hence decreasing the visibility. When the air near the surface becomes saturated, either by cooling it to its dew point temperature or by adding moistureto it, Fog occurs. Depending on how the condensation was created, fog can form in a variety of ways. TheIndo- Gangetic (IG) plains are predominantly affected by radiation fog and advection fog due to varying local conditions. | en_US |
| dc.description.abstract | Fog during winter season over Indo-Gangetic plains is very common and sometimes it creates
hazardous situation and disrupts the life. Fog intensity and its spread forecast is challenging task. Most of
the techniques available are mainly based on the remote sensing observation which is available on
continuous bases and fills data gaps. To forecast precisely we need to validate the fog intensity or spatial
extent during day and night. This work is mainly focuses on the night time fog monitoring with the help of
satellite derived fog products. This product during night time is obtained through channel differencing
(MIR-TIR1) of INSAT-3D /3R channels. Normal threshold was -2.5 degree C or K for fog pixels, but this
work shows that this threshold does not hold good for entire IGP or Indian region, in the case of radiation
fog. The different cases of the season 2020-21 (December-January) have been analyzed with different
thresholds and found that other threshold ranges also significant for fog occurrences over the area. | en_US |
