Open Library is an initiative of the Internet Archive, a (c)(3) non-profit, building a digital library of Internet sites and other cultural artifacts in digital projects include the Wayback Machine, and The Aerosol Lidar is a piggy-back instrument on AROTEL lidar fielded by John Burris and Tom McGee of NASA Goddard Space Flight Center. The light source for the aerosol measurements is a Continuum Nd:YAG laser operating at 50 shots per second. The laser transmits approximately mJ at nm, mJ at nm, and mJ at nm. These eruptions yielded an estimated 20 megatons of SO2, which is three times the amount produced by El Chichon. Lidar measurements taken by the inch lidar system at Langley Research Center. Dual-wavelength aerosol lidar backscatter measurements at Mauna Loa Observatory are used to monitor and characterize the km stratospheric aerosol layer.
An example, showing integrated backscatter measured at Garmisch–Partenkirchen (° N, 11° E) is shown in Figure 2, and clearly demonstrates the massive perturbations to stratospheric aerosol caused by the eruptions of El Chichon () and Mt Pinatubo (), as well as a string of minor perturbations from smaller eruptions.

Dual‐wavelength aerosol lidar backscatter measurements at Mauna Loa Observatory are used to monitor and characterize the 15–30 km stratospheric aerosol layer. The decay of aerosol loading following the El Chichón, Mexico (17°N) and Pinatubo, Philippine Islands (15°N) volcanic eruptions of and , respectively, depends on the phase Cited by:
Airborne lidar measurements of aerosols, mixed layer heights, and ozone during the PEPE/NEROS summer field experiment (SuDoc NAS ) [NASA] on *FREE* shipping on qualifying : NASA. Lidar and in situ measurements of the optical properties of the aerosols locate the layers at the same altitudes. The extinction coefficient is very low in these clean atmospheres, leading to optical thicknesses at nm ( nm) of ± ( ± ) and ± ( ± ) on 23 June and on the night of 6–7 July Cited by: lidar measurements of stratospheric aerosols over menlo park, california; 1, f t october march - n wo 0 u m prepared by o o h philip b. russell, william viezee, and richard d. hake-o stanford research institute tt q 0 menlo park, california n m tws june o0. The optical thickness of stratospheric aerosols also decreased during the corresponding period, from to for the nm wavelength.
