The Online Ray-tracer allows you to determine your own ray-traced delays for observations in the microware spectrum. Ray-traced delays before the year 2008 are based on the ERA-Interim Numerical Weather Models, those from the year 2008 onwards are based on operational Numerical Weather Models, both provided by the ECMWF. Observations before the year 1980 cannot be processed.
The output file (.radiate) will be sent to the email address provided in the form below. For this purpose, we need to save the email address, but it will not be used for any other purpose nor passed to any third party. Mind that due to performance reasons the number of observations is limited to 100 lines.
