EATS 1011 3.0 Introduction to Atmospheric Science YORK UNIVERSITY FACULTY OF SCIENCE Department of Earth and Space Science and Engineering EATS1011 3.0 Introduction to Atmospheric Science Written test 25 minutes ~ 11:00-11:25 AM Vari Hall A 9 th February, 2010 Useful quantities that you may need. Permitted Aids: A calculator and a standard dictionary. Universal gas constant R* = 8.3143x10 3 Jdeg -1 kmol -1 The Gas Constant for a molecule of mass, m, R = R*/m (kmole/kg) The Gas Constant for air is 287 J.deg -1 kg -1 Surface area of a sphere of radius r = 4 π r 2 . Circumference of circle of radius r = 2 π r. Volume, V, of a sphere of radius r: V = 3 4 3 r π 1 AU = 1.50x10 8 km. Speed of light = 3.0x10 8 m/s. Density of air at MSL, ρ air = 1.2 kg m -3 . Molecular weight of CO 2 = 44 Gravity on Mars = 3.7 m s -2 p = ρ RT Density of liquid H 2 O: ρ H2O = 10 3 kg/m 3 The scale height, H = RT/g metres Mean acceleration due to gravity on the Earth: g = 9.8 m s -2 The Hydrostatic Law: p(z) = p(0).exp(-z/H) where H is the scale height Latent heat of Fusion for water ice = 335,000 J/kg Saturated adiabatic lapse rate, Γ M = 6°C /km (nominal).
