DC-8/ER-2 time-series (>1min) within 6min:
only the following aircraft data are considered: - the aircraft heading has to be within a 15 degree half-angle with respect to or opposite to the wind-direction. The wind-direction is prescribed by DC-8 in-situ data. (The DC-8 altitude in km, DC-8 wind-speed in m/s and DC-8 wind-heading [opp.to direction] at the end of the interval are indicated in the right columns - some files also include MASP information on in-situ particle concentrations: order of magnitude of mean and ((max+min)/2).) - the time-difference between data-sets can never exceeds 6 minutes (to minimize problems with cloud evolution) date: month(mm) and day(dd) ---- | counter: number of consecutive 6 second (ER-2 / DC-8) data in the interval | -- (intervals of less than 30 seconds [counter<5] are ignored) | | | | interval: provides start-time (left value) and end-time (right-value) | | times are given in UTC-hours (hh), minutes (mm) and the | | | decimal fraction of a minute (f): hh.mmf -
