N. Larsen (DMI) and J. Rosen (U. Wyoming) — Backscatter measurements of aerosol profiles available for the winter from 1991 to 2002.
N. Larsen (DMI) and J. Rosen (U. Wyoming) – Backscatter measurements of aerosol profiles available for January 1994 – February 1996.
J. Rosen (U. Wyoming) – Backscatter measurements in the winters of 1991 and 1992.
J. Rosen (U. Wyoming) and N. Larsen (DMI) – Backscatter measurements of aerosol profiles available for January 1992–December 1998.
A. di Sarra, T. Di Iorio, and M. Cacciani (U. Rome, ENEA) – Winter-only measurements from September 1991 to 1996. Values currently too small to retrieve. Data are archived under previous PI (G. Fiocco).
J. Rosen (U. Wyoming) – Backscatter measurements of aerosol profiles available from 1996 to 2005.
C. Ritter (AWI) – Multi-wavelength system (excimer and Nd:YAG) making winter measurements between 10 and 45 km since 1991. In 1999 the system was upgraded for tropospheric measurements of aerosol and water vapor. Since 2001 it is a "3+2+1" Raman lidar.
J. Rosen (U. Wyoming) and V. Khattatov (CAO) – Backscatter measurements of aerosol profiles available for the winter from 1989 to 1992.
K. Strong (U. Toronto) — Stratospheric Ozone Lidar system (SOLID) deployed in February 1993 under PI A. Carswell. Nighttime operations only. SOLID has five detection channels, including one Rayleigh channel (353 nm), and one Raman channel (385 nm, installed in 1994) used for aerosol retrieval. Operation suspended for 2002 and 2003. Operations resumed in 2004–2009 on a campaign basis schedule (~2 weeks in February–March) under PI K. Strawbridge. Operation suspended for 2010–2016 due to technical and funding issues. Operations resumed under PI J. Drummond since 2017 on the ~4–6 week period leading up to polar sunrise in January–March and ~2 week period in October–November. Operations since April 2020 have been affected by the lack of on-site support due to the COVID-19 pandemic, funding, and restricted access to the Ridge Lab. Since 2020 the PI of SOLID and PEARL is Kimberly Strong (University of Toronto).
Early data exist in the database for 1994–1998 in NASA Ames format.
