AWAKEN Site B - NREL Thermodynamic profiler (Assist II-11) / TROPoe retrieval
- Dave Turner; Pacific Northwest National Laboratory
This dataset contains daily files with thermodynamic profiles retrieved with the optimal estimation physical retrieval TROPoe (Turner and Löhnert, 2014; Turner and Blumberg, 2019; Turner and Löhnert, 2021). The profiles are retrieved from 30-minute-averaged observations from the NREL ASSIST-II (SN 11) infrared spectrometer. Observations are averaged to reduce noise propagation, although caution is advised during non-uniform cloud conditions. Additional input data in TROPoe is cloud base height from the NREL Vaisala CL51 ceilometer at site A1. In addition to these temporally resolved input data, TROPoe requires an a priori dataset (prior) which provides mean climatological estimates of thermodynamic profiles and specifies how temperature and humidity covary with height as an input (for details see, e.g., Djalalova et al., 2022). The prior is a key component of the retrieval and provides a constraint on the ill-posed inversion problem. A monthly prior was computed from operational radiosonde launches at ARM SGP, OK.
