Retrieving Ancillary Weather Data

The Keck Observatory Archive preserves ancillary weather data for each night, including observatory-generated plots of weather data and CONCAM webpages. Links are also provided to external sources of useful weather data.

All types of ancillary weather data may not always be available for a given night.

To retrieve ancillary weather data, scroll down to the bottom of More Options Search form which looks like the following:

example

Enter a date or a range of dates (not exceeding 30 days), and you will be shown a page with links to all the available weather data for those nights. For each night, the data may include:

Plots of WMKO-observed weather data like temperature and humidity: wx.ps and/or wx.pdf
Guide-star FWHM plot for the night: fwhm.ps and/or fwhm.pdf
A link to the CONCAM pages for that night, if available (no CONCAM data exists for dates after 2007)
Link to Mauna Kea Weather Center's seeing data (available since September 24, 2009)
Link to UH All-Sky Camera's night movie in AVI format (available for 3 months after date of observation)
Link to Atmospheric Attenuation plots from SkyProbe@CFHT (available for dates since April 2, 2001)
