- Parameters
resolution (string, default 'half') – Resolution of the model, either ‘half’ or ‘quarter’ degree.
set_type (string, default 'best') – Type of model to pull data from.
-
model

- Type
string
-
variables
¶ Defines the variables to obtain from the weather model and how they should be renamed to common variable names.
- Type
-
units
¶ Dictionary containing the units of the standard variables and the model specific variables.

Methods
__init__
([resolution, set_type])Initialize self.
cloud_cover_to_ghi_linear

Estimates irradiance from cloud cover in the following steps:
cloud_cover_to_transmittance_linear
(cloud_cover)Convert cloud cover (percentage) to atmospheric transmittance using a linear model.
get_data
(latitude, longitude, start, end[, …])Submits a query to the UNIDATA servers using Siphon NCSS and converts the netcdf data to a pandas DataFrame.

(temperature)Converts Kelvin to celsius.
process_data
(data[, cloud_cover])Defines the steps needed to convert raw forecast data into processed forecast data.
rename
(data[, variables])Renames the columns according the variable mapping.
Retrieves the designated dataset, creates NCSS object, and creates a NCSS query object.
set_location
(tz, latitude, longitude)Sets the location for the query.
Sets the NCSS query location latitude and longitude.
set_query_time_range
(start, end)- param start
Must be tz-localized.
set_time
(time)Converts time data into a pandas date object.
