Atmospheric extinction measurements at Leh in near infrared bands

Abstract

Site survey observations to determine the extinction in the IR bands were carried out at Leh. Mean extinction coefficients obtained from 'two nights' observations in J, H, and K bands are k(J) = 0.05 + or - 0.01; k(H) = 0.04 + or - 0.01; and k(K) = 0.04 + or - 0.01
