Checked data and reactived "live" updates this morning. Unfortunately, data for the following time period was lost: 12/14/2010 (d=348) 06:05 - 12/20/2010 (d=354) 15:00 ============================================================================== 12/14/2010: Station Maintenance: [0002] - Loaded MAWN Program - ABCW (3-hour collection cycle) 11/29/2010: Station Maintenance: [1000] - Weak battery recently detected... replaced with a new battery this morning. 07/01/2010: Station Maintenance: [1100] - Routine maintence, including: - checked/reinstalled 4" soil temp sensor 07/01/2010: Station Maintenance: [1250] - Replaced short-haul modem/FTP with wireless broadband. - Loaded MAWN Program ABCS (30-minute power cycle) - Added "battery voltage" to hourly data table ============================================================================== 04/18/2008: Station Update: - Network connection at Stephenson has been repaired. Station is back online. 04/16/2008: Station Update: - Recent thunderstorm has knocked-out internet connectivity at the Stephenson station. The network at Stephenson should be back up later in the week or early next week. ============================================================================== 05/17/2007: Station Maintenance (sm, jb): - Recent telecommunication troubles that prevented proper data collection has been repaired. Data is once again being collected and updated to the MAWN database. - Due to the telecommunication outage, data for the following time period has been lost: 03/19/07 (Day=78) 08:35 CDT - 04/28/07 (Day=118) 17:50 CDT ============================================================================== 11/03/2005: Station Maintenance (sm): - Communications between the data-collection PC and the data-logger on the weather station had been out for several weeks. Replacement of the short-haul modem components corrected the trouble. Unfortunately, uncollected data was lost for the following time period: 10/04/05 (Day=277) 18:35 CDT - 10/16/05 (Day=289) 16:30 CDT 04/10/2005: Data Quality Note: - It was determined that the clock on the Stephenson MAWN station slowly drifted and was reporting incorrectly for most of the winter. Because of the incorrect clock, the observation times of the data reports are in error. - The clock was corrected on 04/10/2005. - Prior to the correction (Nov 2004 - April 09, 2005), the observation times may be off by several hours. Eventually, all data with incorrect time stamps will either be corrected or removed from the MAWN database. ============================================================================== 03/08/2004: Spring Maintenance (crn): - Site visit - Sensor Check: All OK ============================================================================== 09/30/2003: Data Collection and Data Archive for new station begins First report: Sep 30, 2003 - 00:05 (Day=273) 09/19/2003: New Station Installed: Notes: - leaf wetness B (canopy) - not installed - pressure sensor installed - not active - Soil Moisture Sensor Type - CS616 Water Content Reflectometer - Data Logger Program Loaded: MAWN1C Additional Station Needs: ==============================================================================
