The most requested feature of the IEM is to provide updated daily climodat reports. The reason this was not being done previously was that the underlying data takes a couple of months to make the round trip from the observer to the National Climatic Data Center and to the State Climatologist for processing. Additionally, this data was processed on a monthly basis.

To help fill in the gap between when the most recent quality controlled data is available and your current data needs, I have written a system to produce estimates of the daily observations. Of course, this system is not perfect, but it is a starting point for future improvement. Some notes on the estimating routines for various variables:

High and Low Temperature

These values are derived from the automated airport sensors with a strong weighting towards the quality controlled ASOS daily summary reports. These values are analyzed on a simple grid and then sampled back to produce the point estimate. Previous experience with this technique has shown it to sufficiently well.

Precipitation

The IEM computed daily totals from the National Weather Service stage4 precipitation product are used. A simple grid point sampling provides the estimated observation. This routine will take a bit more fine tuning due to deficiencies with the stage4 product, but it is a start.

Snowfall and Snow Depth

These values are problematic even when the 'observations' exist. In general, I am taking the NWS COOP reports made each morning and assigning them to the previous day. A gridded analysis process is done here as well. These values will be very suspect, but it is about the best that can be done. These data are not currently used in the climodat reports.

So in general, feedback is very much encouraged. These estimates are not being used in the climatologies, nor the daily record products. Once the QC'd data arrives, they will be blown out of the database. I may produce a report in the monthly news article with some summary statistics to see how 'good' these first guess estimates are.

As with everything we do, this data is not official nor provided with warranty. You should seek official sources for high end needs. > Daily Feature +---------------------------------------------- http://mesonet.agron.iastate.edu/onsite/features/cat.php?day=2009-10-21 | Title : Tough to harvest | Date : 21 Oct 06:11 AM | Votes : Good: 16 Bad: 7 +---------------------------------------------- The feature map is the 5 day forecast of precipitation from the HPC. Numerous rounds of showers are expected into the weekend, which is not good news for the large amount of corn and soybean crop yet to be harvested.

IEM Time Machine is a fancy new way to rapidly view current and historical images generated by the IEM. The application presents a menu listing of various products and once selected, you can use buttons and sliders to rapidly transverse the archive of data. At every point along the way, the URL updates allowing you to bookmark or share the link with others to view. The initial feedback I have gotten on this application has been tremendously positive, so I hope you like it as well.

One of the neat features is that this application can utilize images stored on remote servers as well (given that they logically store their images in a timestamp based manner). The application includes a few NWS DIFAX archived products at Colorado State.

Let me know what you think about this and also if you have any favorite web archives you would like added to the app. I'll be adding some more that I know about soon.

This application is exactly what I envisioned doing back when I started the IEM in 2001, too bad it took 8 years to generate this :) +---------------------------------------------- | Title : June COOP data uploaded | Date : 22 Oct 05:00 PM | Author: Daryl Herzmann | URL : http://mesonet.agron.iastate.edu/climodat/ +----------------------------------------------

The quality controlled NWS COOP data for June 2009 has been uploaded to the IEM. Harry Hillaker, our state climatologist, passes along these notes for the month:

The month averaged 69.0 degrees or 0.8 degrees below normal. Precipitation totaled 5.27 inches or 0.63 inches above normal. This ranked as the 54th coolest and 50th wettest June among 137 years of records.

Here is a listing of new daily records set for the month based on data back to 1951.

You can check out this news item for more details on the IEM's estimator. These QC'd observations completely replace the estimated values in the archive.
