Please take our SURVEY

Thank you for participating in our survey. Your input will help the IRI gain a deeper understanding of our user base and utilization of the IRI Data Library and Maprooms. This knowledge will enable us to effectively showcase our reach and impact to potential sources of funding, which is crucial for sustaining and enhancing the IRI Data Library/Maproom services.

The survey is divided into three sections and should take less than 5 minutes to complete. We'll begin by asking about your Data Library/Maprooms usage context, then delve into your usage patterns and reasons. Finally, we'll explore sustainability models for Data Library/Maprooms. Your input will greatly helps us improve our services for you and our community.

Take the survey here.

The Butterworth low-pass filter code has been revisited to support time series of many points like in the example above. This comes with a more robust way of computing the solution. The 3 padding options (px > 0) remain. The option not to pad (px = -1) has been replaced from taping the whole operator to taping its tailing equations only. An additional option (px = -2) now allows to do just nothing to the boundary conditions and therefore apply the Butterworth filer and the Butterworth filter only.

More detailed information at the function documentation:

Note that px = -1 (no padding taped solution) is the one used in the Global Time Scales Maprooms and results remain very similar.

With sadness in our hearts, we remember M. Benno Blumenthal, who died Saturday 15th at night peacefully and with family. We will forever be grateful to Benno for creating the Data Library, for his enlightened contributions to IRI and the field of data science, and for his benevolence to others.

We invite those of you who knew Benno, or who use the Data Library, to share your stories and thoughts about our dear colleague and his legacy. If you would prefer to share more privately, send an email to media@iri.columbia.edu, and we will share with his family and IRI staff.

Recently, a prototype S2S forecast system has been designed at IRI to generate calibrated multi-model ensemble forecasts for tercile precipitation in a similar format to IRI seasonal forecasts.
