Notice of Planned MesoWest Product Changes - Spring 2025

Updated: January 30, 2025 10:00am MST

The MesoWest team has supported since 1997 access to publicly available weather observations through a variety of products accessible through https://mesowest.utah.edu. In order to continue providing support for our core visualization products, we are making changes during Spring 2025 to our product availability. We no longer have the financial and staff resources to sustain all of the software developed over the past 25 years.

MesoWest visualization products (graphical and tabular displays) are intended for public, educational, and research uses. Commercial and operational users should rely on Synoptic Data PBC, as it has the resources to meet 24/7 and operational needs. As a Public Benefit Corporation (PBC), Synoptic Data has a broader mission, resources, and tools to aggregate, process, and distribute data to all sectors of the environmental enterprise to aid with daily activities, operations, and decision-making; save lives; protect property; and educate new generations about Earth's weather and climate. We encourage you to consider using the excellent data viewer now available from Synoptic Data (https://viewer.synopticdata.com/) as opposed to the legacy MesoWest graphical and tabular displays we will continue to support.

We expect to make the following changes prior to May 1, 2025:

1) By March 1 - MesoWest Downtime for Upstream Data Feed Changes

MesoWest will be down at times 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 on the day the downtime takes 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.wrh.noaa.gov/map/), as observational data on that resource originates from Synoptic Data PBC.

2) 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).

3) 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/).

Our team will continue to keep this webpage updated as these efforts progress. We are happy to answer any questions through our support email listed below as well.
