Description: | Below is an overview from Chris Fiebrich, the Mesonet QA manager of the automated quality assurance results for the May 1998 Oklahoma Mesonet data. The May Mesonet data have been posted to your server. There are a few special events that were flagged by the automatic qa that you may want to be aware of. These include: 1. HOLL PRES - May 8 Thunderstorm winds caused a significant pressure drop. This data is accurate so you can ignore the flags. 2. BESS RELH - May 21 A heat burst was measured at the site. It was a fairly localized event so the spatial test flagged the data. You can disregard those flags. 3. MAYR & NEWK WSPD, WVEC - Thunderstorm outflow produced 40+ mph sustained wind observations on the 24th and 25th. This data is believed to be true and you can ignore those flags. 4. FORA RAIN - May 25 The site received nearly double the amount of rainfall as its neighboring sites. Radar confirmed this, so we believe the data to be good. 5. BRIS RELH - May 26 flags were from a wet sensor; the flags are correct and there is no need for continuning concern after the event. 6. CLAY WSPD, WVEC - May 26 flags were caused by strong winds reported at the site during a thunderstorm. You can ignore these flags. -Chris OKLAHOMA MESONETWORK/ARS QUALITY ASSURANCE REPORT for the month of May, 1998 Based upon observations taken at 1800 UTC each day Prepared by Chris Fiebrich (chris@mesnet.mesonet.ou.edu) ================================================================================ A number of pressure problems were corrected during the month of May. Malfunctioning barometers at ALTU and SEIL were replaced, and the barometer tubes at ANTL and STUA were 'de-wormed' (to quote Gary) to correct problems there. The SRAD field was also improved by replacing malfunctioning sensors at TULL, OKMU, and WYNO during the month of May. Some of the soil temperature sensors at BRIS and FAIR fell victim to gopher damage last month. Those sensors were replaced. The monthly QA detected a handful of possible biases in the soil sensors in both the ARS and MESO networks. Those stations included KETC, SHAW, A148, and A157. Those sensors will be investigated in the coming weeks. ================================================================================ TAIR Current: None Added: None Resolved: #1780 MAYR Instrument replaced RELH Current: #1731 CLAY Sensor reporting -7999 on various occassions #1810 KING Monthly QA shows 1.5 - 2.0 C TDEW warm bias #1814 MARS Sensor reporting as high as 110% Added: None Resolved: #1824 HOBA Sensor replaced WDIR Current: None Added: None Resolved: #1770 TULL Sensor replaced due to vandalism WSPD Current: None Added: None Resolved: #1826 FORA Noisy bearings replaced PRES Current: None Added: None Resolved: #1751 ALTU Sensor replaced #1809 SEIL Sensor replaced #1820 ANTL Replaced worm-clogged barometer tube #1836 STUA Replaced worm-clogged barometer tube SRAD Current: #1839 HOOK Reporting -1 for extended periods at night #1843 GRAN Reporting values ~70% too low Added: None Resolved: #1761 TULL Sensor replaced after vandalism #1765 OKMU Sensor replaced to correct 10% bias #1781 MAYR Sensor reporting <0 due to bad TAIR switch #1802 WYNO Sensor replaced RAIN Current: None Added: None Resolved: #1818 PRES New switch installed to fix under-reporting #1829 CAMA Gauge with bucket off bearings replaced #1799 COPA New switch installed to fix under-reporting TA9M Current: None Added: None Resolved: None WS2M Current: None Added: None Resolved: None TS10 Current: None Added: None Resolved: #1790 BRIS Gopher damage; sensor replaced #1777 MEDI Sensor replaced to correct warm bias #1833 FAIR Replaced gopher-damaged sensor TB10 Current: #1779 WILB Monthly QA suggests 4 C cool bias Added: None Resolved: #1782 MAYR Sensor replaced TS05 Current: None Added: #1846 KETC Monthly QA suggests 2-3 C cool bias #1847 SHAW Monthly QA suggests 3-6 C cool bias Resolved: #1811 BRIS Gopher damage; sensor replaced TB05 Current: #1808 WOOD Monthly QA suggests possible 4 C warm bias Added: #1845 KETC Monthly QA suggests 2-3 C warm bias Resolved: None TS30 Current: #1704 EUFA Sensor reporting -9999 due to lightning Added: None Resolved: None ------------------------------------------------------------------------------- ARS QA REPORT ------------------------------------------------------------------------------- TAIR Current: None Added: None Resolved: None RELH Current: None Added: None Resolved: #1813 A182 Sensor replaced SRAD Current: None Added: #1848 A131 Obs too low after sunrise and before sunset Resolved: None RAIN Current: None Added: None Resolved: #1830 A111 Reed switch changed TS05 Current: #1816 A148 Monthly QA suggests possible 2-4 C warm bias #1817 A157 Monthly QA suggests possible 2 C cool bias Added: #1849 A123 PM readings are ~10 C cooler than neighbors Resolved: None TS10 Current: #1831 A157 Spatial QA shows a possible 8 C cool bias Added: None Resolved: #1815 A166 2 C cool bias found; sensor replaced TS15 Current: None Added: None Resolved: None TS30 Current: #1825 A147 Sensor reporting ~5 C too warm Added: None Resolved: #1834 A166 Sensor replaced ============================================================================== LEGEND TAIR Air Temperature measured at 1.5 meters RELH Relative Humidity measured at 1.5 meters WDIR Wind Direction measured at 10 meters WSPD Wind Speed measured at 10 meters PRES Pressure SRAD Incident Solar Radiation RAIN Rainfall TA9M Air Temperature measured at 9 meters WS2M Wind Speed measured at 2 meters TS10 Soil Temperature measured at 10 cm under native sod TB10 Soil Temperature measured at 10 cm under bare soil TS05 Soil Temperature measured at 5 cm under native sod TB05 Soil Temperature measured at 5 cm under bare soil TS15 Soil Temperature measured at 15 cm under native sod TS30 Soil Temperature measured at 30 cm under native sod ============================================================================== Chris Fiebrich July 5, 1998 |
