Values of w calculated from the divergence of minisodar (MS) and radar wind profiler (RWP) horizontal wind profiles were found to agree quite well for an equilateral triangle of measurement sites located at the Argonne Boundary Layer Experiments (ABLE) facility. Values of w averaged over the daytime within the mixed layer were on the order of 0.5 cm/s. Correcting for height differences of 60-100 m among the three measurement sites separated by 63 km was helpful, particularly during windy conditions. A regular output of daily or even hourly values from this network is possible. Upgrades to the ox RWP now being implemented will improve the near-surface radar estimates.
