The National Solar Radiation Database (NSRDB) software includes all the methods for the irradiance data processing pipeline. To get started, check out the NSRDB command line interface (CLI). Refer to the NREL website and the original journal article for more information on the NSRDB. For details on NSRDB variable units, datatypes, and attributes, see the NSRDB variable meta data.
The PXS All-Sky Irradiance Model
The PXS All-Sky Irradiance Model is the main physics package that calculates surface irradiance variables.
The NSRDB Data Model
The NSRDB Data Model is the data aggregation framework that sources, processes, and prepares data for input to All-Sky.
The MLClouds Model
The MLClouds Model is used to predict missing cloud properties (a.k.a. Gap Fill). The NSRDB interface with MLClouds can be found here.
Installation
Option 1: Install from PIP (recommended for analysts):
Create a new environment: conda create --name nsrdb python=3.9
Activate environment: conda activate nsrdb
Install nsrdb: pip install NREL-nsrdb
Option 2: Clone repo (recommended for developers)
from home dir, git clone git@github.com:NREL/nsrdb.git
- Create nsrdb environment and install package
Create a conda env: conda create -n nsrdb
Run the command: conda activate nsrdb
cd into the repo cloned in 1.
Prior to running pip below, make sure the branch is correct (install from main!)
Install nsrdb and its dependencies by running: pip install . (or pip install -e . if running a dev branch or working on the source code)
Optional: Set up the pre-commit hooks with pip install pre-commit and pre-commit install
NSRDB Versions
Version |
Effective Date |
Data Years* |
Notes |
|---|---|---|---|
4.1.1 |
10/28/24 |
None |
Integration with extended MLClouds models. Extended models can perform both cloud type and cloud property predictions. |
4.1.0 |
7/9/24 |
None |
Complete CLI refactor. |
4.0.0 |
5/1/23 |
GOES: 1998-2023. Meteosat: 2005-2022. |
Integrated an improved direct normal irradiance model (FARMS-DNI), described in the paper “Integration of a physics-based direct normal irradiance (DNI) model to enhance the National Solar Radiation Database (NSRDB)” |
3.2.3 |
4/13/23 |
None |
Fixed MERRA interpolation issue #51 and deprecated python 3.7/3.8. Added changes to accommodate pandas v2.0.0. |
3.2.2 |
2/25/2022 |
1998-2021 |
Implemented a model for snowy albedo as a function of temperature from MERRA2 based on the paper “A comparison of simulated and observed fluctuations in summertime Arctic surface albedo” by Becky Ross and John E. Walsh |
3.2.1 |
1/12/2021 |
2021 |
Implemented an algorithm to re-map the parallax and shading corrected cloud coordinates to the nominal GOES coordinate system. This fixes the issue of PC cloud coordinates conflicting with clearsky coordinates. This also fixes the strange pattern that was found in the long term means generated from PC data. |
3.2.0 |
3/17/2021 |
2020 |
Enabled cloud solar shading coordinate adjustment by default, enabled MLClouds machine learning gap fill method for missing cloud properties (cloud fill flag #7) |
3.1.2 |
6/8/2020 |
2020 |
Added feature to adjust cloud coordinates based on solar position and shading geometry. |
3.1.1 |
12/5/2019 |
2018+, TMY/TDY/TGY-2018 |
Complete refactor of TMY processing code. |
3.1.0 |
9/23/2019 |
2018+ |
Complete refactor of NSRDB processing code for NSRDB 2018 |
3.0.6 |
4/23/2019 |
1998-2017 |
Missing data for all cloud properties gap filled using heuristics method |
3.0.5 |
4/8/2019 |
1998-2017 |
Cloud pressure attributes and scale/offset fixed for 2016 and 2017 |
3.0.4 |
3/29/2019 |
1998-2017 |
Aerosol optical depth patched with physical range from 0 to 3.2 |
3.0.3 |
2/25/2019 |
1998-2017 |
Wind data recomputed to fix corrupted data in western extent |
3.0.2 |
2/25/2019 |
1998-2017 |
Air temperature data recomputed from MERRA2 with elevation correction |
3.0.1 |
2018 |
2017+ |
Moved from timeshift of radiation to timeshift of cloud properties. |
3.0.0 |
2018 |
1998-2017 |
Initial release of PSM v3
|
2.0.0 |
2016 |
1998-2015 |
Initial release of PSM v2 (use of FARMS, downscaling of ancillary data introduced to account for elevation, NSRDB website distribution developed)
|
1.0.0 |
2015 |
2005-2012 |
Initial release of PSM v1 (no FARMS)
