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**](/deploying-3d-paws/station-metadata.md) 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.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://3dpaws.comet.ucar.edu/deploying-3d-paws/field-installation-and-deployment.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
