[Bldg-sim] "Maslow's" hierarchy of calibration

[Dru Crawley]

There are high-resolution *free* data sources now for MYs (others call them
AMYs), including:

ERA5-Land from Europe's ECMWF (https://www.ecmwf.int/en/era5-land)
  (Reanalysis data from 1950 to present at 9 km resolution)

 If you want ERA5 data in EPW, Oikolab (https://oikolab.com) provides data
for a fee.


NOAA NCEI ISD Integrated Surface Data (
https://www.ncei.noaa.gov/products/land-based-station/integrated-surface-database
)
  (Global database of weather station-based data from 1900 to present,
replaced soon by GHCN.)

NOAA NCEI GHCN Global Historical Climate Network (
https://www.ncei.noaa.gov/products/global-historical-climatology-network-hourly
)
  (Global database replacing the ISD, more extensive data, fixed format)

Climate.OneBuilding  (https//:climate.onebuilding.org) uses a combination
of ISD and ERA5 for its TMYx -- new data through 2023 for more than 20,000
stations globally coming soon.
