Abstract:

This dataset consists of meteorological variables measured by a research-grade Campbell Scientific meteorological station deployed on the dam of Carvins Cove Reservoir. Carvins Cove Reservoir (Roanoke, Virginia, USA, 37.36944, -79.95778), is owned and operated by the Western Virginia Water Authority as a primary water source. The meteorological variables include photosynthetically active radiation, barometric pressure, ambient air temperature, relative humidity, rainfall, wind speed and direction, shortwave radiation, infrared radiation, and albedo. All variables were measured every minute from 2021-03-29 19:00:00 (YYYY-MM-DD HH:MM:SS) to the end of the dataset at 2022-12-31 23:59:00. We applied quality assurance/quality control protocols to the raw observations, as described in the methods.

Methods and protocols used in the collection of this data package

Description:

Meteorological data were collected using a research-grade meteorological station from Campbell Scientific (Logan, UT, USA) at 1 minute intervals from 2021-03-29 19:00 to 2021-12-31 23:59. All observations are recorded in the GMT -5 time zone (Eastern Standard time) without any time zone changes in the data record.

Site Description and Power:

The Meteorological station was deployed on the concrete walkway on top of the dam at Carvins Cove(37.36944, -79.95778), as such, some of the sensors may be influenced by the dam and structures on the dam itself. Most notably the 4-Component Net Radiometer sensor made up of Shortwave Radiation Up, Shortwave Radiation Down, Infrared Radiation Up and Infrared Radiation Down are hanging over the dam to measure the water below but may be obstructed by the dam. The meteorological station is powered with AC power from the power grid to power the CR3000 data logger and sensors.

Data Quality Assurance/Quality Control (QA/QC) procedures:

Missing data: Major gaps lasting longer than 1 day in the record occurred during these intervals: Sub-daily gaps occurred on 2021-04-09 13:00-13:56, 2021-07-02 14:00-14:41, 2022-04-05 12:00:00-13:56, 2022-04-20 13:00-13:38 and 14:00:00-14:53, 2022-05-12 10:00-10:27,and 2022-09-29 14:00-14:57:00 and 15:00-15:18. Most of these gaps are because of new programs being uploaded to the data logger.

Maintenance Log: We automated QA/QC with an R script (archived with this dataset) that set flags and removed outliers. Smaller gaps in data for a few hours or less due to maintenance occurred throughout the dataset. We set erroneous values due to maintenance as NA (flag 1) in the dataset. For all flag descriptions, see the data table "CCR_Met_MaintenanceLog_2021_2022.csv". There is only one flag per variable in the dataset with all unique flag values; flag 1 for maintenance in some cases overwrote other existing flags. All previously existing NAs due to missing observations other than maintenance were flagged as 2. Negative values were set to 0 for all meteorological variable columns, except AirTemp_Average_C and variables internally measured on the CR300(Record, CCR3000Panel_Temp_C, CCR3000Battery_V), and flagged as 3. Values over 100% were set to 100 for Relative Humidity. Infinite values were set to NA for all variables and flagged as 3. Outliers that were changed or set to NA were flagged as 4 while possible outliers that were not changed and left in the data set were flagged with 5.

Air Temperature: The AirTemp_Average_C variable received intensive QA/QC based on the same QA/QC done for Falling Creek Reservoir Met station (EDI package edi.389.6). We used the data from the initial year of deployment (2021) to develop a linear relationship to predict AirTemp_Average_C from CR3000Panel_temp_C, the Campbell logger panel temperature sensor.The 2021 relationship can be described by the following equation: AirTemp_Average_C = -3.5595812(0.0044426, 1 SE) + 0.9288955(0.0001895)_CR3000Panel_temp_C This relationship's adjusted R-squared value was 0.98. The residuals from this equation were minimum: -6.6734, 1st quartile: -0.6145, median: 0.0319, 3rd quartile: 0.6333, and maximum: 6.6100. If any air temperature values were above or below 4 standard deviations of the residuals from the linear model, we removed that value (flag 4) and substituted it with a new value calculated from the panel temperature and the linear equation. This occurred for 1150 observations during 2022.

PAR Sensor: PAR data during the night that was greater than 12 umol_s_m2 for the average and 1 mmol_m2 were changed to NA and flagged as 4. We used getSunlightTimes function in the Suncalc package in R (Thieurmel, B., Elmarhraoui, A. (2019).suncalc: Compute Sun Position, Sunlight Phases, Moon Position and Lunar Phase. R package version 0.5.0.) to get sunrise and sunset that was used to determine whether the observation was during the day or at night.

Rain Guage: The rain guage was clogged from July 19, 2022 to September 12, 2022 at 11:07 when all the water was released into the gain guage. During this time, we corrected the observations using the rain guage observations from Falling Creek Reservoir during March 29, 2021 19:00-July 18, 2022 00:00. These observations were used for the linear model (y=0.110725x+0.001494). We compared total rain from the raw data which includes when the rain guage was unclogged and the corrected rain totals. The total for that time was 38.1mm and the corrected total was 34.7mm.

Outliers: After previously described adjustments, outliers were set to NA and received 'flag 4' in the dataset, following these outlier thresholds: AirTemp_Average_C > 40.6; InfaredRadiationUp_Average_W_m2 < 150; InfraredRadiationDown_Average_W_m2 > 540; BP_Average_kPa < 95.5; PAR_Total_mmol_m2 > 200; ShortwaveRadiationUp_Average_W_m2 > 1500; ShortwaveRadiationDown_Average_W_m2 > 300; Albedo_Average_W_m2 > 1000; PAR_Average_umol_s_m2 > 3000; PAR_Total_mmol_m2 > 200; WindSpeed_Average_m_s>50; Rain_Total_mm>5.

The outlier thresholds were developed by comparison with the NOAA Roanoke Airport dataset. The Roanoke Airport is located ~6 km away from Carvins Cove Reservoir.

All QA/QC code used for the dataset is archived with this dataset. See QAQC_CCR_Met_2021_2022.R.

Additional Info

Additional Information:

Authorship Statement-CCC is the PI on the project and led the purchasing of the equipment and coordinated equipment deployment. ABP installed all of the sensors and is the point person for the data set for 2022. She also led the maintenance, data management, and QAQC for 2021. DWH helped to install the met station, led the field sampling at CCR, and has done substantial field work at that reservoir in 2021.

Acknowledgments and historical contributions:

This data package has been iteratively updated over time and builds on the many historical contributions of co-authors listed in previous revisions. We thank the Western Virginia Water Authority for providing access to these sites and the Reservoir Group for contributing to fieldwork.
