| Subject: | GAN/GNDRAD/M1 - Incorrect up_long_hemisp |
| DataStreams: | gangndrad60sM1.b1, gangndrad20sM1.a0
|
| Description: | The up_long_hemisp values from the pyrgeometer were much too low, hovering near or just
above 100 W/m^2. This was particularly noticeable when comparing these values to those
derived from the surface IRT.
On 10/05/11, at 0348Z, tower was lowered for removal of PIR SN35836 and installation of
PIR SN35839; tower raised at 0444Z. Following installation of PIR SN35839, data quality
plots indicate proper up_long_hemisp values. |
