This continues through the early morning hours. Some stations will not answer the phone call from the microcomputer during these early morning hours due to problems with the telephone lines themselves. Those stations owned by DWR are maintained by DWR staff or with help from local agencies or people. DWR has no control over making sure the weather data from NM-DWR stations is accurate or reliable. Maintenance standards call for a maintenance visit every 3-4 weeks during the warmer months of the year.
Visits decrease to about every five or six weeks in the cooler months.
The grass which is under each weather station site is mowed regularly to a height of about three inches. The grass is irrigated and fertilized to keep it actively growing. DWR maintained stations are visited by DWR staff out of DWR's District Offices. Stations' sensors are compared against a set of standardized sensors used only for calibrations.
