File List A. Filename: lidar_animation_iop7.gif Short description: Animation of wind and potential temperature structure during IOP7 (26-27 October 2013) of the Second Meteor Crater Experiment (METCRAX II) within a 15° azimuth vertical plane through the crater (location in Fig. 1 of Whiteman et al. 2018). Terrain is indicated by a solid black line and rim elevation by a dot-dash line. Off-plane data are projected perpendicularly onto the plane. 5-min averaging interval. Individual tethersonde soundings (not averaged) are the closest in time within ±7.5 minutes of the averaging interval midpoint. Left sub-figures: Black vectors are 2D (u,w) winds. TS-B wind profiles (blue vectors) have no w-component and are offset from its plain location (moved closer to the crater). TS-SW is at the dashed vertical line. Winds come from dual-lidar retrievals, with red triangles marking the lidar locations. The north rim lidar is the x-coordinate origin. Wind data also come from the RIM tower, the BASE tethersonde, and the SSW4 and SSW2 sites. Color contours (see legend) indicate wind speeds within the plane. Right sub-figures: Potential temperature soundings at sites shown in the legend. The reference height for the potential temperatures is the floor of the basin, and potential temperatures are reported in °C. The sloping dashed line is an isothermal temperature gradient. The animation was produced by Prof. Sebastian W. Hoch at the University of Utah. References: Whiteman, C. D., M. Lehner, S. W. Hoch, B. Adler, N. Kalthoff, and T.

Description of methods used for collection/generation of data: Methods are described in the research paper listed above in SHARING/ACCESS INFORMATION, item 2. 2. Methods for processing the data: Processing is described in the research paper listed above in SHARING/ACCESS INFORMATION, item 2. 3. Instrument- or software-specific information needed to interpret the data: Described in the research paper listed above in SHARING/ACCESS INFORMATION, item 2. 4. Standards and calibration information, if appropriate: 5. Environmental/experimental conditions: Clear, meteorologically undisturbed night. 6. Describe any quality-assurance procedures performed on the data: The original tethersonde, tower, and weather station data have gone through multiple quality checks, with erroneous data deleted. Data plots were checked for quality by trained meteorologists. The lidar data have also gone through multiple software quality checks, with erroneous data deleted. Some wind vectors near the surface coming from the dual-Doppler retrievals in individual frames of the animation are suspect, but still plotted. 7.
