AHATS QC Radiosonde Data


The Advection Horizontal Array Turbulence Study (AHATS) was the fourth in a series of field campaigns aimed at improving large-eddy simulations (LES) of turbulence close to the Earth's surface. The first three Horizontal Array Turbulence Studies (HATS) were, HATS (2002), OHATS (2004) and CHATS (2007). This most recent field campaign, AHATS, took place from May to August 2008 in Kettleman City, CA, the location of the original HATS project. Instrumentation at AHATS included one Integrated Surface Flux System (ISFS) and one Integrated Sounding System (ISS). The ISS was equipped with a UHF boundary layer wind profiler, Radio Acoustic Sounding System (RASS), radiosonde sounding system, and a surface meteorology tower. ISS also deployed a sodar-RASS at the ISFS array three miles downwind of the ISS site. A total of 86 radiosonde soundings were collected during the project, launched from the ISS site.
