Surface Meteorological Station - PNNL 10m Sonic, Physics site-5 - Derived Data

**Overview**

This set provides estimation of the turbulent fluxes obtained with EddyPro v6.2.0 software (15-min averaging).

**Data Details**

Each meteorological station had one sonic anemometer (Gill R3-50, omnidirectional) mounted on top of a 10-m tower. Sensor verticality (within a degree) was verified by the analog inclinometer mounted on the base plate alongside the sonic anemometer. NOTE: the sonic anemometer has been oriented to the magnetic North. The serial data stream was transmitted via radio link (9XTend RF modem by MaxStream) to the data acquisition computer housed in a temperature-controlled enclosure at the base of the 80-m tower.

The original data were stored in flat ASCII files in 30-min pieces (".00." level). The raw data were preprocessed to conform with EddyPro software. All evidently erroneous and/or broken lines were marked as bad. All erroneous or missed data were replaced with "baddata" place holder (99.99), the housekeeping data were stripped off, and the data were split into 5-min portions with no internal time stamp. The preprocessed data are available from the archive as ?.a0? level data.

The current dataset is the result of processing the preprocessed data (?.a0?) with EddyPro v6.2.0 for 15-minute intervals. The dataset contains results and metadata that should fully cover all software settings and options used in data processing.

**Data Quality**

Beyond the Quality Control (QC) procedures implemented in EddyPro, nothing additional is included.
