Zero Power Warming (ZPW) Chamber Prototype Measurements, Barrow, Alaska, 2016Entry ID: Zero_Power_Warming_ZPW_Chamber_Prototype_Measurements_Barrow_Alaska_2016
Abstract: Data were collected during one season of prototyping associated with the development of a passive warming technology. An experimental chamber, the Zero Power Warming (ZPW) chamber, was fitted with apparatus to modulate venting of a field enclosure and enhance elevation of air temperature by solar radiation. The ZPW chamber was compared with a control chamber (Control) and an ambient open air plot ... (Ambient). The control chamber was identical to the ZPW chamber but lacked the apparatus necessary to modulate venting, the chamber vents in the control chamber were fixed open for the majority of the trial period. The three plots were located over Carex aquatilis growing in an area of moderately degraded permafrost. Chambers were placed on the same footprints that were used for a similar exercise in 2015 (no data) and therefore those plots had experienced some thaw and degradation prior to 2016. The following data were collected for 80 days at 1 minute intervals from within two chambers and an ambient plot: solar input, chamber venting, air temperature, relative humidity, soil temperature (at 5, 10 and 15 cm), soil moisture, downward and upward NIR.

Purpose: Data were collected to assess the performance of a warming chamber prototype.

Quality LOGICAL CONSISTENCY REPORT: The data was checked qualitatively and visually for bad and out of range data. Data was found to fall within the expected ranges. The temperature data was checked against the Hobo logger data (15 minute averages) and on average agreed within the expected accuracies of the sensors. To produce the aligned data from the three separate instrument packages missing rows (by minutes) were filled in with NaNs. These occurred in the beginning of the datasets to initiate the time alignment and sporadically for single minutes throughout the season to correct for to clock drift.
COMPLETENESS REPORT: PRI data should be recalculated by each user according to the guidelines in the accompanying ZPW sensor conversions document.
