ARM Aircraft Measurements

Reflectance vs. Transmittance Analysis of Simulated ARM Enhanced Shortwave Experiment Two-Aircraft Measurements of Fractal Clouds

361 Figure 1. Log-log plot of the variance at a given scale, vs. that scale (similar to the power spectrum or a 2nd order structure function). It shows (scale-invariant) ARM cloud liquid water path data plus two computed radiation fields, IPA (“simple theory”) and MC (“better theory”). The MC curve, showing a scale break at the “radiative smoothing scale” 0 . 200-300 m for marine Sc, agrees wit...

Improved Wind Measurements on Research Aircraft

Improved techniques for measuring horizontal and vertical wind components and state variables on research aircraft are presented. They include a filtering method for correcting ground speed and position Inertial Navigation System data with Global Positioning System data, use of moist-air thermodynamic properties in the true airspeed calculation, postflight calculation of the aircraft vertical v...

A comparison of in-situ aircraft measurements of carbon dioxide

This discussion paper is/has been under review for the journal Atmospheric Measurement Techniques (AMT). Please refer to the corresponding final paper in AMT if available. Abstract In this paper we report vertical profiles of CO 2 measured with a cavity ring-down spectrometer (CRDS, Picarro, Inc., 2301-m) on a research aircraft from near ground level to 8 km above mean sea level (a.m.s.l.). The...
