Özet:

 


Soil moisture is an influential parameter in
land surface hydrology and precise soil moisture data that can help researcher
to realize the climate changes and land-atmosphere interactions. A initial
struggle for the utilize of soil moisture data from satellite sensors is their
reliability. It is important to appraise the dependability of those data before
they can be regularly used at a global or local scale. In this study, the satellite soil moisture data was evaluated from the
Soil Moisture Active/Passive (SMAP) over Simineh-Zarrineh Catchment in
Bokan region, NW of Iran. A total of 287 soil samples as ground-based
observations in the time period of 03 April to 03 December 2017 were taken for
SMAP data validation. Results showed
that the satellite data and in situ observation has a good correlation,
with a mean correlation (r) value of 0.63 in total. This correlation level
showed that,
commonly, the SMAP soil moisture products over Simineh-Zarrineh Catchment (Bokan)
have great quality, and it would be valuable for versatile utilization,
including monitoring of land surface, weather prediction, modeling of
hydrological process, soil loess monitoring, and climate studies. The results
reveal that the remotely sensed data demonstrate the good correlation with in
situ observation across the dry land
with mean correlation (r) values of 0.67 throughout the time period.
Particularly, SMAP soil moisture reveal a constant structure for obtain the
spatial distribution of surface soil moisture. Additional researches are necessary for well realizing the
SMAP data.
