Re: NASA POWER

Based on your question you are looking for the hourly global total irradiance (GTI) on an optimally tilted panel for the month of May. The current version of POWER data provides only the monthly mean GTI. If you want to know the hourly GTI on the optimally tilted panel for any given month, you need ...

Re: Normalized Insolation Clearness Index

We currently do not have the Normalized Insolation Clearness Index implemented in the POWER API but we plan to do so in the future. The equation you found on the POWER website was previously used. The previous equation used an approximation for airmass. In the future, when we reimplement the NKT equ...

Re: NASA Prediction Of Worldwide Energy Resources

Thank you for the replay we are working on the issue currently and expect to have it resolved in about a week; we will be updating the API to respond with updated units 'kg m-2 s-1 10^6' instead of the 'kg m-2 s-1' that currently has the precision issue. That unit change is a scaling factor of 1 mil...
