In general large returned power values indicate signal from cloud. Usually examination of both fields reveals cloud occurrence even more clearly. Low values of depolarization ratio (< 0.1) indicate spherical or water particles while greater numbers indicate ice, hail, or large oblate raindrops in some cases. Low depolarization ratios that correspond to low signal most likely indicate tropospheric aerosols.
Data Policy
Please note that the images contained on these pages represent processed lidar data which have, in some cases, received only minimal quality assurance. Thus, the data may contain errors from various sources.
We request that a proper acknowledgement to the "NOAA Environmental Technology Laboratory" accompany the use of this data in any publications and presentations. DABUL is a unique instrument that required a significant development effort. Therefore, if the use of the data in a publication constitutes a major or fairly significant aspect of an article, co-authorship by an ETL scientist is appropriate; please discuss any such planned use with the scientists listed below. We welcome collaborations and will lend our scientific expertise in interpretation and evaluation of the data.
