MesoWest Downtime Notice

Updated: February 25, 2025 6:30am MST

As part of necessary maintenance at the University of Utah, MesoWest is having a downtime today (Tuesday, February 25) to change how it receives data into its legacy database. The data will come entirely from Synoptic Data PBC that bundles all the data into a single data stream. While this change should not impact the majority of weather stations available in our displays, we will reduce our support for some stations outside of North America and multiple same-sensor measurements (e.g., two wind sensors) at the same station. Some other minor changes in data feeds and availability may take place as well. There may be a short gap in data collected into our system today while the data feed resource changes take place.

These changes will have no impact on the actual reception of data by Synoptic Data PBC. Users who require continuous records, or have multiple sensor systems, are encouraged to rely on Synoptic Data's Viewer (https://viewer.synopticdata.com/) as well as Weather API Services (https://docs.synopticdata.com/services/weather-data-api) for accessing complete data from the weather stations that have been available from MesoWest. These changes also will have no impact on data availability for the NWS Weather and Hazards Data Viewer (https://www.weather.gov/wrh/hazards), as observational data on that resource originates from Synoptic Data PBC.

Once this downtime is completed today, MesoWest products should be brought back online with current data available. This page will be updated once MesoWest products are back online.

Additional changes to services on MesoWest will also be taking place over the next few months, with updates on timelines provided on our product webpages as the expected dates move closer:

1) By April 1 - Changes to MesoWest Data Download Services

The Data Download interface available via MesoWest will support downloading no more than one day of data from one station per request. Currently, it is possible to download longer amounts of data for a single station. Users who require extended time period data access are encouraged to explore the data access services offered by Synoptic Data PBC, including a similar interactive Data Download Tool (https://docs.synopticdata.com/services/data-download-tool).

2) May 1 - Sunset of MesoWest User Accounts and Features

In order to reduce maintenance costs and needs, MesoWest will no longer support "MesoWest User Accounts". Our systems will no longer support customized profiles, as well as extended access to products. Users who wish to have a customized user experience are encouraged to explore the offerings available via Synoptic Data's Viewer (https://viewer.synopticdata.com/).

We are happy to answer any questions through our support email listed below as well.
