Title: Notice of Intent for CO2 Weather Station Supplies

Description:

To meet researcher experiment requirements, the system must assess diurnal CO2 and H2O fluxes and associated controlling factors in an agricultural setting, to inform plant growth and water stress tolerance mechanism. High resolution and accurate data metrics including atmospheric CO2 and H20 concentration; air temperature; relative humidity; photon flux density (PAR); net radiation; surface temperature; soil temperature; and wind speed and direction must be measured and recorded once per second. Rugged field equipment including power supply and generation; weatherproof equipment enclosures; and mounting hardware and brackets will be required. All equipment must withstand temperature extremes, dust, and mechanical and electrical shock. Sensors must have the following specifications. The dataloggers must have at least 8 differential plus or minus 5v input channels and achieve 24 bit analog to digital conversion and provide at least 8 GB of onboard storage potential using a removable media data such as SD flash. Dataloggers must be ruggedized and operate from -15 to +70 °C. Temperature/relative humidity sensors must operate between –15 to 60 °C, with accuracies as follows. –15 to 40 °C: ≤90% RH ± (1.3 + 0.003 • RH reading) % RH, –15 to 40 °C: >90% RH ± 2.3% RH, –15 to 60 °C: ± (1.4 + 0.01 • RH reading) % RH, –15 to 60 °C: ± (1.5 + 0.015 • RH reading) % RH, the temperature accuracy must be approximately 0.2% at 23 C or better). PAR sensors must have a sensitivity of approximately 0.01 mV per umol per square meter per second and operate between -15 to 70 C in all humidity conditions. Net Radiometers must operate from –15° to 80°C, their pyranometers would have a spectral range between approximately 385 to 2105 nm up looking and 295 to 2,685 nm down looking with a sensitivity of approximately 0.057 mV per watts per square meter up looking and 0.15 mV per watts per square meter down looking. Net radiometer pyrgeometers would have a spectral range of approximately 5,000 nm to 30,000 nm, and sensitivity of 0.12 mV per watts per square meter. Wind speed and direction sensors must have a speed accuracy of approximately plus or minus 2% and direction accuracy of plus or minus three degrees, with a one-degree resolution, and must operate from -15° to 70°C. Infrared radiometers must operate from -15° to 80°C, with an operating relative humidity range of 0 to 100% RH. Their absolute accuracy must be ±0.2°C (-10° to +65°C) and ±0.5° C (-40° to +70°C), with a uniformity of ±0.1°C (-10° to +65°C), ±0.3° C (-40° to +70°C) and repeatability of ±0.2°C (-10° to +65°C), ±0.5° C (-40° to +70°C). Solar panels must provide a minimum of 90 watts. 12-volt power supplies with regulators must have an operational temperature of -15° to +60°C. Radiation reflecting UV-stabilized weather resistant datalogger housing must be able to contain all necessary components. The assembly and delivery must be provided by the time the cotton emerges. Vendor must provide LoggerNet Software to allow communications and compatibility with existing hardware and programs. All equipment must be compatible with existing custom in-house datalogger code written in CR Basic, and data downloaded from the systems must be formatted for analysis using in-house developed Python and Excel code written specifically for this project.
