Description: | On 7/20/2011 2211GMT Ops replaced the Gndrad upwelling shortwave instrument (PSP) but the calibration coefficients weren't changed until 07/25/2011 1842GMT. The up_short_hemisp data will be reprocessed. Old SN/cal:31294F3 / 113.59 W/m2/mV New SN/cal:32014F3 / 116.43 W/m2/mV Apply the following correction factor to each up_short_hemisp data point during this time period: new value [W/m^2]= old value [W/m^2]* (116.43/113.59) |

DataStreams: | nsaskyrad20sC1.a0, nsaskyrad60sC1.b1, nsaqcrad1longC1.c1, nsaqcrad1longC1.s1 |
Description: | On 7/20/2011 starting 2229GMT ops replaced the Skyrad shortwave instruments (PSP/8-48/NIP) corresponding to the datastreams (down_short_hemisp, down_short_diffuse_hemisp, short_direct_normal) but the calibration coefficients weren't changed until 07/25/2011 1842GMT. Data will be reprocessed. Longwave data are unaffected. down_short_hemisp Old SN/cal:31414F3 / 119.23 W/m2/mV New SN/cal:32015F3 / 111.44 W/m2/mV down_short_diffuse_hemisp Old SN/cal:33258 / 110.85 W/m2/mV New SN/cal:33375 / 115.31 W/m2/mV short_direct_normal Old SN/cal:31759E6 / 118.88 W/m2/mV New SN/cal:31344E6 / 121.77 W/m2/mV Apply the following correction factor to each instrument data stream below during the specified time period: down_short_hemisp 7/20/2011 2238GMT to 7/25/2011 1843GMT: correct value [W/m^2]= old value [W/m^2] * (111.44/119.23) down_short_diffuse_hemisp 7/20/2011 2229GMT to 7/25/2011 1843GMT: correct value [W/m^2]= old value [W/m^2] * (115.31/110.85) short_direct_normal 7/20/2011 2248GMT to 7/25/2011 1843GMT: correct value[W/m^2]= old value [W/m^2] * (121.77/118.88) |
