Abstract / Description:Results from experiments measuring the
contribution of the surface layer to the optical
seeing at the Observatorio Astronómico Nacional
at San Pedro Mártir (OAN-SPM) are reported.
Microthermal sensors placed at 7 levels on a
15-m-high instrumented mast were used to measure
the structure constant of the refractive index
C[n]2. The integrated seeing parameter was
measured with a Differential Image Motion Monitor
during 23 nights. Log-normal statistics were
found for the seeing with mean of 0.98 arcsec and
median value 0.84 arcsec . The contribution of
the surface layer (2.3 to 15 m) to the total
optical turbulence has a mean value of 16
