CAMS 20 Monthly Summary Report

Use this form to retrieve monthly summaries of hourly average data collected at CAMS 20. Although this is our most current data, it is not considered official until it has been certified by our technical staff. This information is updated hourly.

This web page provides the most current hourly averaged data available. Our convention for time-tagging data is the beginning of each hour. For example, values shown for the noon hour are based on measurements take from noon to 1:00 p.m.. The noon average will not be calculated until after 1:00 p.m.. The noon average will be then be available on our external server after 1:30 p.m.. This results in an apparent one hour time lag in the data. We also present our data in Local Standard Time for each measuring site. For most of Clark County this is Pacific Standard Time. During Daylight Savings, this introduces another apparent one hour time lag in the data.

Advanced Reporting Options

Select a time format:

Choose to have the report generated in either an AM/PM format or in a 24-hour format. This time format only affects the labeling in the table header and not the report contents. The report is always generated in Local Standard Time (LST) for each reporting station.


Select a report format:

Use the buttons below to select a report format. You may select to view the monthly summary in either a tabular format (web-page formatted table) or as a comma-delimited file. If you want to cut and paste data from this web page into another application, such as a spreadsheet, select the comma-delimited format. To generate a report with each table on a separate page, select the printer friendly format.

Selecting the Comma-Delimited option will override the following selections: time format is set to 24 hour; the day output in the report contains a full month/day/year; there are no color highlights; no highlight legends are displayed.

Selecting the Printer Friendly option will override the following selections: there are no color highlights; no highlight legends are displayed. In addition, the report does not use HTML formatting commands and each table is separated by a page break command. This option is designed to allow you to print the summary report with each table on a single page. This option produces a Rich Text Format (RTF) stream that is directed to the word processor you choose. When your browser starts the external application (word processor you selected), select the "Open it" option and click on the OK button - the word processor you selected will be opened and the report loaded. The report is formatted for landscape mode with minimal margins. The font for each table is selected based on the calculated maximum width of the report. Print from your word processor just like you would any other document. If you do not have Microsoft Word, or WordPerfect installed on your computer, select the "Generic RTF" word processor type. Your browser will prompt you for what to do. Select "Pick App". From this point you should be able to use any word processor that understands RTF.

Select Statistics:

You may choose any of the statistics below to be included in the report. Daily statistics will appear in columns at the far right of the report. Monthly statistics will appear at the bottom of each table.

Select Highlighting Options:

For ozone and PM-2.5, you may choose to have the background cell color highlighted based on the values reported. The highlight colors correspond to air quality ratings.

For ozone, the rating scale is based on projected 8-hour averages.

For PM-2.5, there is a national 24-hour standard. The daily average (if you have selected this statistic) will be highlighted based on this national standard. The DAQEM has developed a 1-hour standard based on historical data. All hourly data will be highlighted based on the DAQEM 1-hour standard.

You can control specific color highlighting in the report. You may choose to have validated data highlighted in the report. Validation indicates that an DAQEM technician has physically reviewed the data.
