Subject: | NSA/ISSSONDE/C1 - Reprocess: Pressure variable name unstable |
DataStreams: | nsaisssonde10sC1.a1, nsaisssondeC1.a1 |
Description: | During the time period referenced, the variable for pressure should have been recorded as "pres", but instead was recorded as "press" for the first 8 months and then was unstable for the next 2 months with some headers reporting pressure as "pres" and others reporting pressure as "press". From 1/14/02 onward the variable name is consistently "pres". Data quality are not affected, but the variability may prove challenging for users. A reprocessing request has been submitted. |

Subject: | NSA/SONDE/C1 - Incorrect surface altitude |
DataStreams: | nsaisssonde10sC1.00, nsaisssonde10sC1.a1, nsaisssondeC1.00, nsaisssondeC1.a1 |
Description: | The value of the station altitude (relative to mean sea level) is incorrect in all NSA radiosonde files prior to 2/14/2004. The correct value is 8 m. The incorrect value can be different. Prior to 4/24/2002 (in platform nsaisssonde...) it was given as 12 m. From 4/24/2002 to 2/13/2004 (in platform nsasondewnpn...) it is almost always given as 27 m (sometimes [rarely] 17 m). |
