You may have noticed some banding in the solar radiation data over the last couple of days. When I asked John Mecikalski what was happening, he provided the following explanation:

“Over the previous few days, the NASA GHCC feed of GOES data has been corrupted by some nearby signal, which they cannot determine. Hence, for a period of time each day the data are messed up and noisy. NASA is working feverishly to determine how to correct this problem.”

For convenience, the download site now includes images of yesterday’s solar radiation for Puerto Rico (INSOLRICO.JPG) and Hispaniola (INSOLCARB.JPG).

Here are four irrigation discussion groups you may want to consider subscribing to. I have been a member of Irr-L for years and have found it invaluable. The information below came from the following website: http://www.trickle-l.com/new/onthenet/

There are four distinct irrigation discussion groups: Irrigation-L, Trickle-L, Salinity-L and SoWaCS.

The purpose of Irrigation-L is to cover technical aspects of irrigation like design, hydraulics, and system layouts. It is also open for topics like irrigation management, socio-cultural, political and economic questions relevant to irrigation.

Trickle-L focuses on all aspects of drip irrigation technology that is sometimes referred to as Microirrigation.

Salinity-L discusses the management practices of saline soils along with more detailed discussions of salt movement in the soil and crop salt tolerance.

SoWaCS or Soil Water Content Sensors is a discussion list which obviously focuses on methods and techniques used to measure soil water content and soil water potential.

All of the above discussion groups are operated by a listserver. A listserver automatically distributes an e-mail message from one member of the list to all other members on the list. When you subscribe to a list, your name and e-mail address is automatically added to it. To subscribe to any of the four lists above, send in the E-mail message (without the quotes), “subscribe (name of list) your name to the following addresses:

For IRRIGATION-L: LISTSERV@listserv.gmd.de
TRICKLE-L : http://list.vi-dev.com/listinfo/trickle-l
For Salinity-L: LISTSERV@crcvms.unl.edu
For SoWaCs: Majordomo@aqua.ccwr.ac.za

To me the above instructions are a bit confusing. I will try to clarify the instructions in a subsequent post.
