SEEING HORIZONTAL MAPS TEMPORAL EVOLUTION

Seeing horizontal map extended on a 50km x 50km square surface centred on LBT (represented with a black dot). The seeing is integrated over three different vertical slabs:
    TOTAL SEEING (εTOT) - [dome-20000]m
    BOUNDARY LAYER SEEING (εBL) - [dome-600]m
    FREE ATMOSPHERE SEEING (εFA) - [600-20000]m
The seeing in each pixel is obtained integrating the CN2 along the zenith and covering the temporal range [dusk,dawn]. The animations show the temporal evolution with 1-hour steps (in UT and MST). The black iso-lines represent the heights of the Digital Elevation Model (DEM).
