SFMS Insights: SPIKE - Subscribe to NSIDC alerts

**Describe the task**
Investigate if we can subscribe to alerts from the NSIDC so we're aware of issues with snow data.

**Acceptance Criteria**
- [ ] Alerts (if available) go to the PSU inbox

**Additional context**
- NSIDC: https://nsidc.org/home

Start by reviewing the NSIDC site and its available alert or subscription options, then determine how alerts could reach the PSU inbox. Done means confirming whether NSIDC alerts are available and documenting or enabling a path to the PSU inbox, including the limitation if no suitable alert service exists.
