Sampling Frequency. 1.4 Source coding algorithm *
Sampling Frequency. The East Boulder Oversight Committee shall determine the frequency of chemical and physical monitoring at each site location. Currently, sites EBR-001, EBR-002, DF-01 are monitored quarterly. Currently, sites EBR-003 and EBR-004 are monitored monthly. Currently, site EBR-005 is monitored in the first and third quarters of each year. At the time SMC commits to construction of the Boe Ranch facilities, chemical and physical monitoring at sites EBR-005, EBR-007, EC-01 and EBR-008 shall resume quarterly frequency.
Sampling Frequency. Sampling for public health monitoring under this plan will occur at each of the identified sites as listed in Table 2: Upper Klamath Lake and Keno, X.X. Xxxxx, Copco, and Iron Gate reservoirs Public health sampling in Upper Klamath Lake and Keno, X.X. Xxxxx, Copco, and Iron Gate reservoirs will begin in May. Public health samples will be submitted for cell-count analysis only from May (ODEQ and PacifiCorp sites only), June, and July and analysis of all samples will be rushed. After July, no cyanobacteria samples will be analyzed. Samples will continue to be sent to EPA for microcystin analysis throughout the season. Public health memos will include the microcystin toxin data as it is received from the EPA lab. Monitoring data from previous annual public health sampling efforts (2005- 2016) indicates that Microcystis cell counts and/or microcystin levels in non-river samples (Iron Gate and Copco reservoirs and Upper Klamath Lake) typically remain elevated until cooler weather and shorter days terminate the blooms.
Sampling Frequency. The Stillwater Oversight Committee shall determine the frequency of chemical and physical monitoring at each site location.
Sampling Frequency. The sampling frequency should be equal to at least 8 FH. In the case of analogical recording, when the recording and reading speeds are different, the sampling frequency can be divided by the speed ratio.
Sampling Frequency. The frequency of sampling is expected to correspond with the extent of conservation measures required by the adopted acres target defined for each Partner according to their adoption rate and extent of enrolled lands. Partners reporting actual adopted acres above-and-beyond their minimum target are not required to monitor any additional points above the threshold associated with their adopted acres target. Sampling frequency is intended to provide a reasonable sample size that can characterize results of conservation measures, while also being reasonably accomplished by rights-of-way and land managers who are also tasked with overseeing the safe implementation of conservation measures and covered activities, as well as sustain operations of their infrastructure. The following recommended frequency is based on expected extent of adopted acres, as well as potential Partner feedback received during development of this agreement.
Sampling Frequency. During this study, ERG is proposing sampling every 1 in 3 days at each of these sites. Over the course of two months, this short-term sampling schedule will yield approximately 20 sampling days, which we believe is a sufficient number of data points to calculate an estimate of long-term concentrations for a number of air toxics. This type of “short-term” average is currently being used by EPA in their evaluation of monitoring data for the Schools Air Toxics Initiative. These estimates will then be compared to various public health exposure levels to assist in determining whether or not we recommend that monitoring be extended to an annual period. Each sample conducted will be 24-hour samples targeting VOCs and SNMOC. Specific monitoring at the sites will be:
Sampling Frequency. EO data on optical properties of inland waters are typically available every few days (e.g. Sentinel 2 and 3). For algorithm calibration, the temporal match with the satellite overpass should be short, ranging from 1 hour to ~3 days. The ideal time difference depends on the temporal variability of the water quality parameter of interest, so defining a specific frequency is context dependent. A recommendation is to derive match-ups within 3 hours. Measurements taken during late morning (local time) are closest to the overpasses of optical sensors across the globe. For providing match-up with EO data, sampling frequency of in-situ data should by high, ideally, every day or every few days. Permanent measurement installations help to provide a large number of match-ups, though not all parameters can be measured with automated systems. Sampling frequencies of monthly or less are likely to have fewer close match-ups with satellite data, unless monthly in-situ sampling programmes are explicitly designed to ensure match-up with satellite overpasses. Sampling frequency varies a lot across the different variables and depends on the measurement technique. The frequency ranges from every few minutes for parameters that can be measured automatically using sensors (e. g. temperature, dissolved oxygen, chlorophyll-a fluorescence, turbidity) to parameters that need to be processed in a laboratory, which are more typically sampled at weekly to monthly frequency (e.g. microbiology, cyanobacteria, chlorophyll-a concentration, suspended matter concentration). The possibility of making campaigns though the year or years, also determines the sampling frequency, from months to years. Monthly sampling is most common and corresponds to the sampling frequency typically required for monitoring inland water quality by regulations (e.g. the European Water Framework Directive). However, hourly to weekly sampling can be required for some water quality parameters for research or investigative monitoring purposes to adequately capture natural variability (e.g. diurnal changes in dissolved oxygen or turbidity changes associated with storm events). Permanent measurement stations such as AERONET-OC stations and the GLEON network provide very valuable data sets as they enable match-ups with each overflight and provide key data on reflectance and/or water quality in very many different conditions (light, sun/viewing angles, atmospheric conditions).
Sampling Frequency. Suspended and bedload sediment sampling must be conducted once every 3 years at all monitoring site locations designated in this Section 1.19 of this Appendix at the same time of year.
Sampling Frequency. The above-stated sampling shall be performed for each separate installation of CIPP. One sample from each individual pipeline liner installed.
