- •
We compared soil moisture from two microwave satellites to in situ data in Canada.
- •
SMOS soil moisture was within 10% of in situ data and captured trends well.
- •
Aquarius soil moisture had higher errors in places with frequent wet/dry cycles.
- •
Surface satellite soil moisture showed a stable consistent pattern with in situ data.
- •
In situ networks with more stations had better relationship with satellite data.
