Spring is coming – tune up your weather stations

The 2019 growing season will be here in another few weeks. Now is the perfect time to give your Rainwise weather stations a tune-up. Use the checklist below to make sure you are getting the best possible data feed from your machine.

If your Rainwise station is getting old (>6 years) consider replacing the machine if this decision suits your farm management needs. A 2017 online survey of current NEWA users found that 75% of growers are saving money on their spray bill with average annual savings of $4,329 from reduced pesticide applications and $33,048 in avoided crop losses.

To get in touch with Rainwise support for station servicing or replacement of your weather station sensor assembly please reach out to the RainWise Inc. Service Department for consultation by phone (207) 801-4039 or email service@rainwise.com.

Spring weather station tune up checklist

Set a maintenance schedule. Check your weather station every 2 or 3 weeks through the growing season. Choose dates in advance and add to your calendar or planner.

Clean the solar radiation sensor. The diffuser can be cleaned with a damp cloth. Replace the sensor if has turned yellow.

Check the anemometer and weather vane. Make sure the anemometer (spinning fan) and weather vane move freely in all directions. Set the weather vane to zero on due North.

Check the leaf wetness sensor. Examine the plastic board and electrodes for corrosion, cracking or weathering damage.

Check the relative humidity sensor. Verify the accuracy of RH measurements by looking at NEWA values on mornings that are rainy or have heavy dew.

Clean the rain gauge. Remove leaves, nests, insect, spider webs and other debris. Set a schedule. Watch this video and learn more about tipping bucket maintenance.

Tune up your weather station

Remember to check your weather station before the 2018 growing season begins to get the most from NEWA models and resources. Read this article and be sure your instrument is ready to go. Contact support@newa.zendesk.com if you are unable to resolve problems or have questions.

Winter weather station maintenance

As the 2017 field season comes to a close, it’s time to give your stations some TLC.

I must emphasize the importance of keeping stations clean and in good working condition. Even small errors in sensor measurements like rainfall and temperature can lead to larger NEWA model miscalculations over time.

Here are some useful preventive maintenance tips. You can also download a maintenance checklist.

  1. Clean the rain gauge tipping bucket. Leaves, insects and other debris can clog the drain, causing an error in rainfall measurements. Do this not only in the fall but again in the spring and at least twice during each growing season. To learn more about tipping bucket maintenance, watch this YouTube video (https://www.youtube.com/watch?v=_7Q3xL2vvPg&feature=youtu.be)

  2. Clean the solar radiation sensor. The diffuser can be cleaned with a damp cloth. If the diffuser is yellowed, contact Rainwise support for technical assistance.
  3. Check the anemometer and weather vane. Both the anemometer (spinning fan) and weather vane should also move freely in all directions. Set the weather vane to zero on due North.
  4. Check the leaf wetness sensor for damage. Examine the plastic board and electrodes for corrosion, cracking or weathering damage. Also look at station leaf wetness data on NEWA. If wet periods seem to be missing or incorrect based on your field observations or experience, contact Rainwise support for technical assistance.
  5. Check the RH sensor. Verify that RH measurements are accurate by looking at RH values on dewy or rainy mornings using the NEWA website. If values are low or missing, the temperature/RH sensor may need to be replaced. Contact Rainwise support for technical assistance

Rainwise recommends a two-year calibration cycle for their weather station. As of October 2017, NEWA recommends that you contact Rainwise support at (207) 801-4039 or 1-800-762-5723 before dismantling and sending your station to the factory for repairs. Recent national weather events have caused a backlog of station service requests. This will minimize station downtime.
