A Quick and Easy Way to Merge LI‑1500 Light Sensor Logger Files

A Quick and Easy Way to Merge LI‑1500 Light Sensor Logger Files

The LI-1500 Light Sensor Logger can log data manually, continuously, daily, or over a user-defined period. Therefore, a data set for a project can consist of many separate files. For data analysis, we often need to merge all, or parts of, these files into a single file. Here are the steps to do so:

1. Start the fv7x00 File Viewer program. If you do not have it, you can download it here:

Studying Invasive Species: the LI-6800 Trial Winner

Studying Invasive Species: the LI-6800 Trial Winner

Invasive species can alter ecosystems and food chains. None are quite like Tamarisk, also known as salt cedar. Tamarisk sucks up a ton of water and deposits salt when it sheds its leaves, making the soil inhospitable to other plants. “There’s not much left when Tamarisk comes to town,” says Randy Long, a PhD student at the University of California, Santa Barbara.

Randy’s doctoral dissertation is studying the local adaption of Tamarisk to environmental gradients, as well as interactions of…

Solar Eclipse Data from LI-COR

Solar Eclipse Data from LI-COR

On Monday, the LI-COR campus was in the path of totality for the August 21, 2017 solar eclipse. Here are data collected during the eclipse at our campus in Lincoln, Nebraska, USA. Even though cloud cover obscured our direct view of the eclipse, there were observable differences in light intensity, photosynthesis measurements, and environmental flux during totality.

The partial eclipse began around 11:37 AM CST, with totality happening from 1:02 PM to 1:04 PM. The eclipse was over by 2:37…

R3 and HS Sonic Anemometer Configuration

R3 and HS Sonic Anemometer Configuration

The Gill R3 and HS series of anemometers can be connected to the LI-7550 to collect data on a USB drive.  This can facilitate remote data monitoring and collection through the available Ethernet connectivity.

The anemometer will have to be preconfigured to send data out in the required format. This can be achieved using any serial communication software like Windows HyperTerminal or Tera Term (which can be downloaded for free here). You can also use the WindCom or RCom2…

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…
