Hi Vikram

Ahmad’s advice got me past where I was stuck previously: Make sure you go to Data Access Viewer and then select first thing "Sustainable Buildings" under "Choose a User Community"

I’ve delved a little deeper and note that converting via E+ gives the file headers and works out soil temperatures and some other header information. I also reduces precision to 1DP.

I tried this for the UK, Manchester and found that Solar was truncated to “99999” from July 2021 onward. So I may stick with my current “Shinyweather” solution (see below).

A comparison with the Copernicus derived weather available at https://shinyweatherdata.com/ yielded the following Root mean square errors:


DBT

DPT

RH

Pressure


1.4

1.2

8.6

429.2

 

You can calculate RMSE in a single cell quite neatly using the following formula (it may need to be input using ctrl-shift-enter, depending on your version of Excel)…

=(AVERAGE((RANGE1- RANGE2)^2))^0.5

Kind regards

Chris

We’ve been testing this out – so far it works great. Anyone else use it? One thing we noticed is that the epw file that you download is in a format that some programs will reject. Our workaround was to use the energyplus weather converter to convert it to csv and back to epw – that seemed to fix any issues.

Has anybody used this yet? I think it’s out of Beta now.

I just tried using the service (  <https://nam02.safelinks.protection.outlook.com/?url=https%3A%2F%2Fpower.larc.nasa.gov%2Fapi%2Fpages%2F%3Furls.primaryName%3DHourly&data=04%7C01%7Cvikram%40olsonkundig.com%7C6f552e0bd7d3419cd45908d9ad9f3f26%7Cd5b3df51a48046ba8f92ef77dd2c7d72%7C1%7C0%7C637731722487347116%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C2000&sdata=xgCP4OB5MCgNTsq15BcfpOuZVdh0Wplb0LIjRbLVwpg%3D&reserved=0> https://power.larc.nasa.gov/api/pages/?urls.primaryName=Hourly ) and it threw me an error.

{"header":"The POWER Hourly API failed to complete your request. A required backend service is unavailable at the current time please try again later. If the issue persists please email  <mailto:larc-power-project at mail.nasa.gov> larc-power-project at mail.nasa.gov with the request URL and any other relevant information.","messages":"The POWER Data Archive is unreachable (Surface Request)."}

I’m not seriously using this at the moment. Just playing 😊

NASA POWER can generate EPW files for a location in the Power Data Access Viewer.

I haven't used the data but I was not aware of this previously so I thought I would share, see below.

Dear NASA POWER user,

The Prediction Of Worldwide Energy Resources (POWER) Project is transitioning to a new hosting environment and is requesting user feedback on the Web Services Beta. The Beta, which will eventually become POWER Web Services Portal Version 2, utilizes the new version of data including the latest NASA satellite analysis sources for surface fluxes (solar and thermal infrared). In addition, the following enhancements to data services have been implemented:

1.       Single location, user specified time period, hourly data availability (including the .epw output data format)

2.       Single location, user specified time series processing for various time averages using the newest input data 

3.       Single location, user specified time period, long-term variability and anomaly reports (including ASHRAE® building climate zone indicators for climate monitoring)

4.       Single location, user specified time period ASHRAE® Climate Design Condition report

5.       Single location, regional, and global user specified time period ASHRAE® building climate zones processing (visualization capability in the NASA AGOL <https://nam02.safelinks.protection.outlook.com/?url=https%3A%2F%2Fnasa.maps.arcgis.com%2Fhome%2Fgroup.html%3Fid%3D4b75def515df430980faebca6a007465%23overview&data=04%7C01%7Cvikram%40olsonkundig.com%7C6f552e0bd7d3419cd45908d9ad9f3f26%7Cd5b3df51a48046ba8f92ef77dd2c7d72%7C1%7C0%7C637731722487357071%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C2000&sdata=ZweIhI591b%2Fb1SYdSJjgwITXgNadWrL8wYC%2BvxZ0zRg%3D&reserved=0> )

Users of the POWER Data Access Viewer (DAV) should experience no major impacts on usability during this migration process. For users of the custom POWER Application Programming Interface (API), there will be substantial improvements in the responsiveness, usability, and standard compliance of the API endpoints. This includes an updated path based Uniform Resource Locator (URL) system, enhanced Uniform Resource Identifier (URI) query keywords, a streamed response of the requested data format (no longer requiring you to find the requested data format download link within the JSON response). 

For more information on how to integrate the Version 2 of the POWER API Services Catalog, please navigate to the POWER Services Catalog Documentation <https://nam02.safelinks.protection.outlook.com/?url=https%3A%2F%2Fpower.larc.nasa.gov%2Fbeta%2Fdocs%2Fservices%2Fapi%2F&data=04%7C01%7Cvikram%40olsonkundig.com%7C6f552e0bd7d3419cd45908d9ad9f3f26%7Cd5b3df51a48046ba8f92ef77dd2c7d72%7C1%7C0%7C637731722487367017%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C2000&sdata=%2FnEiGhss5NJdF74T4mBTQRE3WjW43Vetq%2BNQOsLewTo%3D&reserved=0>  link on the Beta site.

This migration is expected to be completed on 07/01/2021. Once migrated, the POWER Services Catalog Version 1 will be deactivated and only Version 2 will be supported going forward.

Beta Site (Version 2): https://power.larc.nasa.gov/beta/ <https://nam02.safelinks.protection.outlook.com/?url=https%3A%2F%2Fpower.larc.nasa.gov%2Fbeta%2F&data=04%7C01%7Cvikram%40olsonkundig.com%7C6f552e0bd7d3419cd45908d9ad9f3f26%7Cd5b3df51a48046ba8f92ef77dd2c7d72%7C1%7C0%7C637731722487367017%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C2000&sdata=2JVqP7q6DwoJEgiH%2FuaYILOBZRg4pNK532Hd896hnJ8%3D&reserved=0>  

Please explore, utilize, and provide feedback to the POWER Project Team <mailto:larc-power-project at mail.nasa.gov> . We appreciate your input on any bugs or data issues as well as improvements or additional tools needed. 

For any questions regarding this transition, please reach out to POWER Project Team <mailto:larc-power-project at mail.nasa.gov> .

Sincerely, 

The POWER Project Team
