Journal Article
Rimvin, G. R., Paulson, K. S., & Bellerby, T. (2018). Estimating one-minute rain rate distributions in the Tropics from TRMM satellite data (October 2017). IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 11(10), 3660-3667. https://doi.org/10.1109/JSTARS.2018.2869322

© 2008-2012 IEEE. Internationally recognized prognostic models of rain fade on terrestrial and Earth-space extremely high frequency (EHF) links rely fundamentally on distributions of 1-min rain rates. In Rec. ITU-R P.837-6, these distributions are es... Read More about Estimating one-minute rain rate distributions in the Tropics from TRMM satellite data (October 2017).

A method to estimate trends in distributions of 1 min rain rates from numerical weather prediction data (2015)
Journal Article
Paulson, K., Ranatunga, C., & Bellerby, T. (2015). A method to estimate trends in distributions of 1 min rain rates from numerical weather prediction data. Radio science, 50(9), 931-940. https://doi.org/10.1002/2015RS005651

It is known that the rain rate exceeded 0.01% of the time in the UK has experienced an increasing trend over the last 20 years. It is very likely that rain fade and outage experience a similar trend. This paper presents a globally applicable method t... Read More about A method to estimate trends in distributions of 1 min rain rates from numerical weather prediction data.
