Welcome to the new DEOS Monthly Summaries page!

We’ve made major improvements, including:

• ✅ CSV downloads for easy data access
• ✅ Monthly statistics for DEOS hydrologic parameters
• ✅ Improved quality control of the underlying data

We’re still updating our historical climate stats, so data is currently available from 2015 onward. The full dataset (back to 2004) will be available later this year.
