SGP/EBBR - EBBR E22 Soil Moistures Negative
DataStreams:sgp30ebbrE22.b1, sgp15ebbrE22.b1
Because of the lack of rain, all soil moistures were negative during much 
of the period.  The negative soil moistures caused soil heat storage and
thus average soil heat flux to be smaller than they should have been.  The
sensible and latent heat fluxes were therefore reduced slightly 
(approximately 0-5%).

The affected data are:

15 minute: r_sm1, r_sm2, r_sm3, r_sm4, r_sm5
30 minute: sm1, sm2, sm3, sm4, sm5, c_shf1, c_shf2, c_shf3, c_shf4,
           c_shf5, cs1, cs2, cs3, cs4, cs5, ces1, ces2, ces3, ces4, ces5,
