Available dates for Climate Data?

Dear organizers & fellow competitors,

thanks a lot for hosting this challenging and interesting competition!
I’m trying to connect to the NOAA API to pull climate data, but unfortunately I only seem to be able to get data from 2021/03/21, when inserting earlier dates I get an error message:

<?xml version="1.0" encoding="utf-8"?>BlobNotFoundThe specified blob does not exist.


Is there any way to access earlier data that I’ve been missing so far?

Thank you very much and best regards!

Hi @DavidEis and @Nyantaro! Thank you for flagging this.

We’ve added a second approved data access location for HRRR data. You should be able to pull climate data for earlier dates using the new AWS endpoint instead of the planetary computer endpoint. There are more details on the problem description page.

Good luck, please don’t hesitate to reach out if you run into any other trouble!

To get started, here’s a snippet of example code to pull data from the AWS access point instead of the Planetary Computer. It uses the same general approach that is outlined in the Planetary Computer example notebook (also linked from the problem description page).

sector = "conus"
cycle = 12  # noon
forecast_hour = 1  # offset from cycle time
product = "wrfprsf"  # 3D Pressure Levels
sample_date = "20190826"  # August 8 2019

file_path = f"hrrr.t{cycle:02}z.{product}{forecast_hour:02}.grib2"
url = f"https://noaa-hrrr-bdp-pds.s3.amazonaws.com/hrrr.{sample_date}/{sector}/{file_path}"
print(f"Full URL: {url}")

r = requests.get(f"{url}.idx")
idx = r.text.splitlines()

> Full URL: https://noaa-hrrr-bdp-pds.s3.amazonaws.com/hrrr.20190826/conus/hrrr.t12z.wrfprsf01.grib2

Oh! Really thanks for your regard!!

Hi @kwetstone,

thank you very much for adding the additional data source - the new AWS endpoint works great :slight_smile:

Best regards
