SEEING TEMPORAL EVOLUTION
Temporal evolution of the seeing integrated in different vertical slabs between the sunset and the sunrise:-
TOTAL SEEING (εTOT) - [dome-20000]m
BOUNDARY LAYER SEEING (εBL) - [dome-600]m
FREE ATMOSPHERE SEEING (εFA) - [600-20000]m
On the x-axis is time in UT (bottom), in MST (top). Mountain Standard Time MST=UT-7. Data points frequency is 2 minutes. Data points are re-sampled at a frequency of 20 minutes after a 1-hour moving average. The error bars (black line) are the sigma over the 20 minutes sampling, computed before the moving average.
For those cases in which there are in-situ real-time measurements, the website displays the following outputs:
- BLACK LINE: model forecast displayed at 14:00 MST.
- GREEN LINE: real-time measurements treated with a 1h moving average as the forecasts.
- RED LINE: short time scale forecasts computed each full hour and extended on the successive four hours (see 'forecast legend').
