In readiness the temporary stations and radar calibrators have been installed this week. And fortuitously we got a good amount of rainfall last weekend bringing soil moisture levels from near zero up to around 0.4 to 0.5v/v. Over the past week this has dried to between 0.2 and 0.3v/v with further rain expected this weekend. In any case, we now have some very interesting soil moisture patterns to explore!

Apart from the pasture sites with typical autumn time grass conditions, the cropping fields are mostly bare soil, and either being worked for planting or have recently been seeded. This gives a nice base of low crop conditions/bare soil which will be contrasted against the much more mature crops we anticipate in SMAPEx-5.
Only one more week until we start sampling!!
