Research Note


The impact of urbanization is assessed by comparing values of the radiation parameters at an urban location with those of a rural site. Urban Delhi was divided according to land-use and the effects of urbanization was studied on incoming short-wave (K↓), albedo, incoming longwave (L↓, outgoing longwave (L↑), and net radiation (Q*), were individually studied at four representative sites (Rural, Commercial, Residential and Industrial). MaximumK↓ was observed in the rural and commercial areas whereas highL ↓ was observed in the commercial and industrial locations. High depletion ofK ↓ of the order of 13% was observed for the industrial location in the winter season. An increase ofL ↓ in, the industrial location is of the same order as that of the commercial location, i.e. 20%. The residential location shows quite moderate (4.6%) depletion ofK ↓ in comparison with other sites.
