Notice of Planned MesoWest Product Changes - Spring 2025

Updated: February 25, 2025 2:55pm 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 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/).

Completed Changes:

Upstream Data Feed Changes (Late February)

In late February, MesoWest changed how it receives data into its legacy database. The data into MesoWest systems now originate entirely from Synoptic Data PBC that bundles all the data into a single data stream. While this change should not have impacted the majority of weather stations available in our displays, we did reduce our support for some stations outside of North America and multiple same-sensor measurements (e.g., two wind sensors) at the same station.

These changes had 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.



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.
