Study Notes
Chemical Transformations in the Atmosphere
- Krypton (Kr) concentration is 1 ppm with a molar mass of 83.80 g/mol.
- Hydrogen (H2) has 0.5 ppm concentration, molar mass 2.02 g/mol.
- Nitrous oxide (N2O) is present at 0.3 ppm with a molar mass of 56.03 g/mol.
- Ozone (O3) levels range from 0 to 0.1 ppm, with a molar mass of 48.00 g/mol.
- Hydroxyl (OH) radicals play a crucial role in oxidizing these chemicals, facilitating their removal from the atmosphere.
Atmospheric Chemistry and Condensation
- Some nitrogen and sulfur compounds transform into aerosol particles, which are later removed by precipitation, contributing to acid deposition.
- Aerosols and cloud droplets account for a small portion of atmospheric mass but are significant for water vapor condensation in the hydrological cycle.
Overview of the Earth's Atmosphere
- The atmospheric pressure at a height reflects the mass above that point.
- Total mass estimates of the atmosphere can vary by approximately 0.4% based on calculations involving vertical and meridional variations.
Optical Properties of the Atmosphere
- The atmosphere allows solar radiation to pass through while blocking outgoing radiation, contributing to the greenhouse effect.
- This effect keeps Earth's surface warmer than it would be without an atmosphere.
- Clouds and aerosols lead to about 22% of incoming solar radiation being backscattered into space without absorption.
Weather and Climate
- Atmospheric phenomena with timescales shorter than a few weeks are classified as weather, with longer timescales relating to climate.
- The saying “Climate is what you expect; weather is what you get” distinguishes between expected long-term trends and short-term conditions.
- Climate variability encompasses changes over months or years, informed by climatological-mean statistics that summarize typical seasonal or yearly conditions.
Fundamental Thermodynamic Variables
- Key variables in atmospheric studies include pressure (p), density, and temperature (T).
