The stations are roughly equidistant from each other, and have temp &amp; precip data for the exact same times. Before, I typically used the Kriging tool inside 3D analyst. This time when I try it, it simply creates a single-colored square between the outer stations.</P><P></P><P>This is my working environment in ArcPro, with the 5 stations:</P><P><IMG alt="" class="image-1 jive-image j-img-original" src="https://community.esri.com/legacyfs/online/451075_Capture.PNG" /></P><P></P><P>What would I put in the Parameters on the left? Is there perhaps another, better interpolation method in ArcPro?</P></BODY></HTML> Fri, 21 Jun 2019 18:28:47 GMT https://community.esri.com/t5/science-questions/how-to-interpolate-weather-data/m-p/849539#M93 MalcolmLittle1 2019-06-21T18:28:47Z Re: How to interpolate weather data https://community.esri.com/t5/science-questions/how-to-interpolate-weather-data/m-p/849540#M94 <HTML><HEAD></HEAD><BODY><P>cc <A href="https://community.esri.com/migrated-users/29300">Kevin Butler</A>‌ <A href="https://community.esri.com/migrated-users/310609">Dan Pisut</A>‌?</P></BODY></HTML> Sat, 22 Jun 2019 18:18:23 GMT https://community.esri.com/t5/science-questions/how-to-interpolate-weather-data/m-p/849540#M94 DawnWright 2019-06-22T18:18:23Z Re: How to interpolate weather data https://community.esri.com/t5/science-questions/how-to-interpolate-weather-data/m-p/849541#M95 <HTML><HEAD></HEAD><BODY><P>Malcolm,</P><P>You've run into a classic problem with interpolating meteorological data, a small number of sampling locations with a lot of measurements across time.&nbsp; None of the kriging methods in ArcGIS Pro deal with time explicitly.&nbsp; I suspect what is happening is that the Kriging tool is getting all of its neighbors from the same location so it sees very little variation in the data.&nbsp; Do you have access to the Geostatistical Analyst extension?&nbsp; If so, I suggest trying the Empirical Bayesian Kriging tool.&nbsp; It has an environment setting (Coincident Points) that will summarize all of your temporal observations down to a mean value.&nbsp; Five points is not a lot of information to build any interpolation model on.&nbsp; You many need to 'help' the model by providing additional explanatory variables.&nbsp; You can do this with either the EBK Regression Prediction tool or Forest Based Classification and Regression tool.&nbsp; This Learn lesson might help:&nbsp;<A href="https://learn.arcgis.com/en/projects/analyze-urban-heat-using-kriging/">https://learn.arcgis.com/en/projects/analyze-urban-heat-using-kriging/</A>&nbsp; Cheers.</P><P><A href="https://community.esri.com/migrated-users/156352">Dan Pisut</A></P></BODY></HTML> Mon, 24 Jun 2019 16:40:48 GMT https://community.esri.com/t5/science-questions/how-to-interpolate-weather-data/m-p/849541#M95 KevinButler1 2019-06-24T16:40:48Z Re: How to interpolate weather data https://community.esri.com/t5/science-questions/how-to-interpolate-weather-data/m-p/849542#M96 <HTML><HEAD></HEAD><BODY><P>Or look back in history and first approaches of dealing with climate data and allocation to points</P><P><A class="link-titled" href="https://pro.arcgis.com/en/pro-app/tool-reference/analysis/create-thiessen-polygons.htm" title="https://pro.arcgis.com/en/pro-app/tool-reference/analysis/create-thiessen-polygons.htm">Create Thiessen Polygons—Help | ArcGIS Desktop</A>&nbsp;</P><P><A class="link-titled" href="https://en.wikipedia.org/wiki/Alfred_H._Thiessen" title="https://en.wikipedia.org/wiki/Alfred_H._Thiessen">Alfred H.
