Description: | Comparison of the dowelling hemishperic solar broadband flux estimated
from the unshaded PSP (down_short_hemisp) and that derived from the
combination of the NIP (short_direct_normal) and shaded PSP
(down_short_diffuse_hemisp) showed significant differences (greater
than 60 W/m^2) at times on June 23, 1997. These differences appear
to be due to questionable data from the NIP (short_direct_normal) that
may have been caused by rainfall on that day. The NIP values recorded
values as low as -25 W/m^2 in proximity to when the SMOS recorded
precipitation. After the first precipitation event, the NIP appeared
to be recording lower values during sunnier periods that may be due
to collected precipitation in the NIP affecting the amount of solar
radiation reaching the sensor |
