Just since I prepared the files for some eye inspection, I thought we could add them here too.
Below you find the data underneath each other and in the same scale. The data is recorded at the Mokwakwaila office and at the Morwatshela high school. The plots are spanning from June 2013 until today. Notice that one of the sensors were installed some three months later than the other. This explains the long straight line from June to November 2013.
With the two graphs in front of us, we can at least see some correlation between the values with the naked eye.
The office station also has a rain gauge and we can see that there was quite heavy rain at the end of January. This also forms a peak in the soil moisture at the school. If we look at the accumulated rain over seven day periods over the year, Mokwakwaila received 75 mm during end of January. Interestingly, there was an earlier rain fall, flood, on Jan 6, where 61 mm was registered during 6 hours.
Just for the interested, a quick comparison of the different soil moisture values are given in the figure bellow. The curves can be identified from above (green: deep@school, yellow: shallow@office, red: deep@school, blue@office).
