Ground-based measurements of total ozone column amount with a multichannel moderate-bandwidth filter instrument at the Troll research station, Antarctica
Sztipanov, Milos; Tumeh, Lubna; Li, Wei; Svendby, Tove Marit; Kylling, Arve; Dahlback, Arne; Stamnes, Jakob J.; Hansen, Georg; Stamnes, Knut (Journal article; Peer reviewed, 2020)Combining information from several channels of the Norwegian Institute for Air Research (NILU-UV) irradiance meter, one may determine the total ozone column (TOC) amount. A NILU-UV instrument has been deployed and operated ... -
Laser light propagation in a turbid medium: solution including multiple scattering effects
Stamnes, Knut; Li, Wei; Stamnes, Snorre; Hu, Yong; Zhou, Yingzhen; Chen, Nan; Fan, Yongzhen; Hamre, Børge; Lu, Xiaomei; Huang, Yuping; Weimer, Carl; Lee, Jennifer; Zeng, Xubin; Stamnes, Jakob J. (Journal article; Peer reviewed, 2023)We have shown that solutions to the radiative transfer equation for a homogeneous slab yield a zenith radiance reflectance that for collimated beam incidence in the nadir direction can be expressed in terms of the lidar ... -
Machine Learning-Based Retrieval of Total Ozone Column Amount and Cloud Optical Depth from Irradiance Measurements
Sztipanov, Milos; Krizsán, Levente; Li, Wei; Stamnes, Jakob J.; Svendby, Tove Marit; Stamnes, Knut (Journal article; Peer reviewed, 2024)A machine learning algorithm combined with measurements obtained by a NILU-UV irradiance meter enables the determination of total ozone column (TOC) amount and cloud optical depth (COD). In the New York City area, a NILU-UV ... -
Method for retrieval of aerosol optical depth from multichannel irradiance measurements
Sztipanov, Milos; Li, Wei; Dahlback, Arne; Stamnes, Jakob J.; Svendby, Tove Marit; Stamnes, Knut (Journal article; Peer reviewed, 2023)We present, to the best of our knowledge, a new method for retrieval of aerosol optical depth from multichannel irradiance measurements. A radiative transfer model is used to simulate measurements to create the new aerosol ... -
A new algorithm for simultaneous retrieval of aerosol and marine parameters in coastal environments
Stamnes, Knut; Li, Wei; Fan, Y.; Hamre, Børge; Frette, Øyvind; Folkestad, Are; Sørensen, Kai; Stamnes, Jakob J. (Peer reviewed; Journal article, 2013)We present simultaneous retrievals of aerosol and marine parameters in coastal areas from ocean color data using the OC-SMART algorithm, Ocean Color: Simultaneous Marine and Aerosol Retrieval Tool. OC-SMART uses a one-step ...
