Last winter was rather warm and very wet in western Europe while in the US and Canada it was cold or rather very cold!
We looked at the SMOS data collected over Europe as obtained from CATDS and Arnaud extracted the wettest value over ten day periods (here ascending orbits) as shown on the animation below ( to see the animation click on it)
Fig1: maximum soil moisture (around 6 am) over successive ten day periods from January 1 to February 10 2014 as measured by SMOS.
One can see that in Ireland, SW England , W France and SW France soil moisture saturates (value at or above field capacity) indicating sodden soils with heaving pounding. If we look at the product proving minimum value fro the descending orbits we see that even at the driest if was not always completely dry.
Fig2: minimum soil moisture (around 6 pm) over successive ten day periods from January 1 to February 10 2014 as measured by SMOS.
Even in the driest state, note that in some areas the soils are still quite wet.
These picture show how we can track saturated to flooded areas with SMOS. Also note the impact of RFI in some areas , giving rather dry soils when / where not expected.
As presented in several posts already, the team in Hamburg has developed a method to estimate thin sea ice with SMOS data. This method complement very nicely the Cryosat retrievals. The team has been a step further and is now investigating, within an ESA project, how such daily information could be used operationally to help routing boats. The idea is to select the shortest path from one point to the other as a function of ice thickness and distance , both impacting fuel consumption.
A field experiment is currently starting as depicted here to validate the approach.
So SMOS might also help save energy?!
Dear Smos Blog followers…
We have been somewhat silent these last few weeks (months!) because activities were somewhat frantic!
We have been through many iterations to improve drastically the SMOS level 1 and preparing the new 6nn version for all levels (1 to 3) which are undergoing final tests before overall evaluation and beginning of implementation and reprocessing (more detailed news on this soon).
We have been active to prepare the next steps (the mission extension review took place at ESA and is for very soon at CNES) we work on the other missions (Aquarius and SMAP to be launched on November 5th) the follow on concept both for the near term (the so called SMOS follow on) and the future (the SMOS Next concept).
SMOS soil moiture in near real time is almost there … stay tuned
and obviously some good science is coming..
We will try to resume now more regular updates and please fill free to submit topics it will be out pleasure to post them!
The SMOS team
As you very well know the CATDS products are delivered in NetCDF format an in the ESE grid projection. Recently we updated the format to the EASE Grid 2
So Arnaud has prepared two new routines to cover this change!
You will thus find on this blog 2 new matlab functions
geo2easegrid (EASE 2.0)
netcdfload (EASE 2.0)
to read L3 products from CATDS adapted to the new EASE Grid .
