Using a Cradlepoint Modem with LI-COR Eddy Covariance Systems

Using a Cradlepoint Modem with LI-COR Eddy Covariance Systems

LI-COR Eddy Covariance systems can be used with a variety of modems and M2M devices for remote communication. LI-COR provides Sierra Wireless modems for remote communication. However, there are a variety of other devices that can be used. Please refer to our technical note on cellular communications for Eddy covariance.

Cradlepoint manufactures various kinds of M2M/IoT and In-Vehicle Routers that can be used for this purpose. These modems are not officially supported or supplied by LI-COR, but here are…

Changes to LI-8100A Wireless Communication

Changes to LI-8100A Wireless Communication

Wireless communication is an excellent way to use the LI-8100A Automated Soil Gas Flux System in the field to start and stop logging, and view the data in real time. For wireless communication, the system has always relied on a peer-to-peer connection using a Cisco wireless card inserted into one of the PC card slots in the LI-8100A Analyzer Control Unit. Apple iOS devices, like the Windows Mobile and PALM devices before them, were able to easily connect using peer-to-peer networking.

However,…

Downloading LI-8100A Data to a Mac

Downloading LI-8100A Data to a Mac

The LI-8100A Interface Software is only available for Windows computers.  Fortunately for Mac OS X users, there are still a few ways to download LI-8100A data onto a Mac.  You can save the data to a Compact Flash card on the instrument, then eject it and use a card reader to import the data directly.  You can also use our SoilFluxPro software (available for Windows and Mac) to connect to the instrument and download data.  There are two connection options…

How to Correct an Erroneous Calibration for the LI-7700 Open Path Methane Analyzer

How to Correct an Erroneous Calibration for the LI-7700 Open Path Methane Analyzer

The LI-77000 analyzer provides the facility for users to calibrate using standard calibration gases. This option can be used to assure users that the instrument is performing according to specification. However, a mistake or an error in the calibration of the LI-7700 will result in incorrect zero (kz) and span (ks) multipliers. As a result, the computed methane density according to equation 6-12 of the LI-7700 Instruction Manual will be incorrect.

How to Routinely Check an Eddy Covariance System to Ensure Normal Operation

How to Routinely Check an Eddy Covariance System to Ensure Normal Operation

Most eddy covariance (EC) systems are deployed in remote areas and exposed to harsh environmental conditions. During years-to-decades of continuous operation, potential issues related to contamination, power, animal damage, lightning, and other natural events such as fog and precipitation can arise. Aging of the hardware and out-of-date software could also become issues. In order to minimize data loss, routinely checking your EC system should be part of your maintenance plan. Considering time consumption and effectiveness, here are our recommendations:

  1. Check…
