# Field Installation and Deployment ### Overview This section provides guidance for installing and verifying a 3D-PAWS station in the field. Field deployment includes: * preparing the site * installing the station * positioning instruments correctly * verifying system operation * documenting installation conditions Careful installation ensures the station produces **reliable and representative environmental data**. *** ### Prepare the Site Before installation, confirm that the site meets the requirements described in *Site Selection*. The location should provide: * open exposure for wind measurements * unobstructed rainfall collection * appropriate surface conditions for temperature and humidity measurements * sufficient solar exposure for the power system * adequate communications coverage The site should also be safe and accessible for installation and maintenance. *** ### Install the Station Assemble and install the station using the procedures described in the [***Installing the Weather Station***](#instruction-slides-for-installing-the-weather-station) section below. Once installed, confirm the following: * station is level and stable * sensors are securely mounted * rain gauge is level * cables are properly routed and protected * solar panel is connected and receiving adequate sunlight * system powers on successfully *** ### Instrument Placement Guidelines Proper instrument placement is critical for accurate measurements. Even when sensors are functioning correctly, poor siting can introduce significant errors. #### Rain Gauge * Install in an open area, away from obstructions * Avoid placement on the leeward side of the station or nearby structures * Ensure the gauge is level * Keep clear of trees, buildings, sprinklers, and overhangs *** #### Wind Sensors (Anemometer and Wind Vane) * Install in a location with minimal obstruction * Position sensor arms perpendicular to prevailing winds where possible * Avoid turbulence from nearby structures * Ensure sensors rotate freely **Wind Vane Alignment**\ The wind vane must be aligned to true north for accurate wind direction measurements.\ → See *Wind Vane Alignment* *** #### Radiation Shield (Temperature / Humidity / Pressure) * Install in well-ventilated, open air * Avoid shading from the station structure or nearby objects * Ensure full exposure to ambient conditions *** #### Solar Panel * Orient toward maximum solar exposure * Avoid shading throughout the day * Consider seasonal sun angle and local conditions *** ### Verify Station Operation Before leaving the site, confirm that the station is operating correctly: * data logger is powered and online * data transmission is functioning * sensor readings are updating * all components are secure Sensor values should appear **reasonable for the installation location**. *** ### Verifying Sensor Data Using Local Climate Norms Compare observed values to expected conditions for the location. Climate normals (typically 30-year averages) provide a useful reference:\ → [**https://www.ncei.noaa.gov/products/wmo-climate-normals**](https://www.ncei.noaa.gov/products/wmo-climate-normals) #### Example Checks * Temperature significantly above expected\ → possible radiation shield exposure or siting issue * Rainfall inconsistent with conditions\ → possible gauge leveling or obstruction issue * Pressure outside expected range\ → possible configuration or sensor issue Some variation is expected, but persistent discrepancies should be investigated. *** ### Installation Checklist Use the [**3D-PAWS Installation Checklist**](https://docs.google.com/document/d/1--PBiW-t_eiH6AI-fDY2usEfYwW2dc-Q79F7PT1GA9w/edit?usp=sharing) during deployment to confirm that: * sensors are installed and positioned correctly * wiring and power connections are secure * required site measurements are recorded * system checks are completed before leaving the site *** ### Station Metadata After installation, record station details using the [**3D-PAWS Metadata Form**](https://docs.google.com/document/d/1q_UKSZHwp8ADDljWSyT0m7x3b6vQNsZgFbbu2g5cdOE/edit?tab=t.0): → See [**Station Metadata**](https://3dpaws.comet.ucar.edu/deploying-3d-paws/station-metadata) Accurate metadata is essential for interpreting observations and maintaining the station over time. *** ## Instruction Slides for Installing the Weather Station > **NOTE:** This section is being updated from building and installing the station to just installation after pre-assembly in the lab. The slide deck will be split into two sections and updated soon. {% embed url="" %} ### Tutorial Videos for Installing the Weather Station This video is part of a playlist that demonstrates building the 3D-PAWS station.
