Automatic Data Flagging
All environmental monitoring data goes through an automatic screening at time of arrival and is only added to averaged data if it has passed the first automatic checks. Exclusion of non-ambient measurements is made through flags attached to the data samples. The underlying measurements are still present and can be recovered. Automatic recognition and flagging on non-ambient data is critical for near real-time delivery of data to the public. LEADS EMS gives you the confidence that data collected and displayed to the public meets exacting quality standards – even before review by a human. Instrument changes can also be quickly and easily scheduled. Automatic data flagging segregates these instrument responses from ambient measurements as well.
A good example for viewing automatic data flagging and how LEADS EMS handles this is the Yearly Summary Report. For an excellent example, follow the link below and select the Austin Northwest site (CAMS 3) for 2007 and then select ozone as the parameter of interest. You will see examples of automatic data rejection, automatic instrument changes, as well as data that has been manually validated. Below is a link to this report live on the Texas Commission for Environmental Quality web site:

Graphical Data Validation
Data can be manually edited and validated by a human using the tools encompassed within LEADS EMS. Data validation is a key step in data collection in accordance with regulatory standards. Validators are able to add or remove flags to data, add notes, change slope and intercept and more using the LEADS EMS Manual Validation Interface. Validators are assigned permissions to edit or flag data and after data is inspected, the data validator must sign off that the data has been manually validated. Validated data is clearly indicated on the web based reports.
Automatic Alerting
LEADS EMS is a resourceful tool for environmental alerting. When parameters such as ozone or PM2.5 reach concentrations that exceed health standards, automatic alerts can be generated and sent to local health officials, schools, nursing homes, and hospitals. Similarly, alerts can be generated and disseminated when concentrations of dissolved oxygen drop significantly in nearby water sources, which can lead to suffocation of aquatic species and diminished watershed quality. TCEQ has an ozone alerting system that has been in place since 2000. Follow the link below to view current warning levels in Texas:

Web Based Reports
LEADS EMS provides hundreds of web-based interfaces including graphical representations and reports ready to provide you access to the data you collect. These cover all aspects of the system from operational information such as electronic operator logs and communications summaries, to automatic calibration reports, to general data reporting pages, to highly specialized data reports. The IPS MeteoStar web and visualization tools are very robust and have proven themselves with continuous operation 24 hours a day, 7 days a week, for over 10 years. Below are links to some of the more popular public web reports:

Specialized Reports
The impending problem of air quality and ozone exceedance days has become a concern in many urban areas. LEADS EMS generates various types of ozone products including 4 Highest 8 hour Ozone Concentrations, Daily Maximum 8 hour Average, and 8hour Ozone High Value Days. LEADS also offers an ozone potential forecast which accounts for favored ozone development conditions. Below are links to several specialized reports:

Hourly Air Quality Index (AQI)
Each hour, regional AQI reports are generated with current conditions. AQI maps are updated with current conditions indicated in each box and colored according to parameter concentration. Small boxes beneath the large one indicate other parameters monitored in that particular region. Each AQI box is representative of all monitoring stations in that region. To get a detailed report for a particular region, the user may interactively select an area of interest to zoom into. Follow the links below for examples of these reports:
