| Description: | Energy monitor reading for laser output is at zero for intermittant
one-minute averaged shots during this flagged data period. From the
lidar equation progressing to normalized relative backscatter the
laser energy is required and is a denominator. Therefore a value of
zero will render the product as infinite. Shots where this has taken
place are left as zeros. It is suggested that the time periods
19970902 2211 - 19970903 1359,
19970907 1445 - 19970908 1544,
and
19970910 2142 - 19970910 2355
be avoided for any quantitative analysis. |
