TL;DR: In this article, the most important instrumental errors are linked with detector nonlinearity, digitization errors and alignment errors, which will largely determine what the minimum and maximum achievable altitude ranges, and what the achievable spatial and temporal resolutions actually are.
Abstract: It has often been claimed that the DIAL method is self calibrated. For tropospheric ozone this is true only if the following effects are properly accounted for: 1) differential extinction and backscatter due to molecules, 2) differential extinction and backscatter due to aerosols, and 3) differential absorption by other gases (see Chapter 2). In addition to the methodological limitations, technical limitations of the lidar instruments have to be taken into account. The most important instrumental errors are linked with: detector non-linearity, digitization errors and alignment errors (see Chapter 3). For a particular lidar system, these errors will largely determine what the minimum and maximum achievable altitude ranges, and what the achievable spatial and temporal resolutions actually are.

TL;DR: In this article, the measurement strategy and a validation technique based on internal consistency for routine lidar measurements of tropospheric ozone are outlined and compared to balloon soundings from DeBilt and Uccle.
Abstract: The measurement strategy and a validation technique based on internal consistency for routine lidar measurements of tropospheric ozone is outlined. Routine lidar measurements are presented and compared to balloon soundings from DeBilt and Uccle and to a time series of free tropospheric ozone values from Uccle.
