What quality control is applied to the data?
The ACARS data stream is very high quality, with less than 2% of the data showing problems. Nevertheless, all data shown on the web site or available for download have been quality-controlled at GSD. This processing includes interpolating location and time information to those data, such as high-resolution ascent data, that lack it. Data that fail quality control are indicated by a special color on the web plots, and several quality control and interpolation flags are available in the netCDF data that indicate exactly what test(s) and interpolation each datum was subjected to. Details of the quality control are available here.
