Laravel NOAA

Laravel NOAA is a wrapper for the NOAA's climate data API at https://ncdc.noaa.giv/cdo-web/api/v2.

Installation

From your source directory, use the following command:

$ composer require epixian/laravel-noaa

Publish assets:

$ php artisan vendor:publish --tag=epixian-laravel-noaa

Configuration

Add the following to your .env file:

NOAA_TOKEN=YOUR_NOAA_TOKEN_HERE

Register for a token at https://www.ncdc.noaa.gov/cdo-web/token.

Usage

For a full listing of API request parameters, visit: https://www.ncdc.noaa.gov/cdo-web/webservices/v2.

Required

{requestType}()

where {requestType} is one of:

• datasets
• dataCategories
• dataTypes
• locationCategories
• locations
• stations
• data

Sets the type of request to be generated.

get()

Executes the request and returns a JSON-decoded result (typically an array) depending on the API response. Note: requires a request type method to be previously called and must be the last call when chaining methods.

// fetch all datasets
$response = \Noaa::datasets()->get();

Alternatively, you may supply a single string argument to get() representing an id belonging to that request type (valid for all request type methods except data():

// fetch dataset with id of 'GSOM'
$dataset = \Noaa::datasets()->get('GSOM');

Optional

from(startDate)

startDate is a string containing a valid ISO formatted date (e.g. '2010-10-02'). Note: this field is required for the data() request type.

to(endDate)

endDate is a string containing a valid ISO formatted date (e.g. '2010-10-07'). Note: this field is required for the data() request type.

orderBy(field, direction)

field is a string containing one of: id, name, mindate, maxdate, or datacoverage.

direction is an optional string containing either asc (default if omitted) or desc.

limit(number)

Defaults to 25 if omitted.

offset(number)

Defaults to 0 if omitted. Note: the API returns results with indexes starting at 1. offset(0) and offset(1) produce equivalent results.

Laravel-style helpers

A number of method aliases are provided for convenience:

• latest() - equivalent to orderBy('maxdate', 'desc')
• oldest() - equivalent to orderBy('mindate', 'asc')
• skip(number) - alias of offset()
• take(number) - alias of limit()
• where(field, value) - sets a generic parameter (see https://www.ncdc.noaa.gov/cdo-web/webservices/v2)

Request constraints may be chained together to refine or limit the data returned:

$dataset = \Noaa::datasets()->from('1970-10-03')->to('2012-09-10')->take(50)->get();

Additional constraint methods specific to the request type are detailed below.

Datasets

// or
$dataset = \Noaa::datasets()->withDataType(['ACMH', 'MLY-TAVG-NORMAL'])->get();

withLocation(id)

id is a string containing a single valid location ID, or an array of strings representing multiple location IDs.

$dataset = \Noaa::datasets()->withLocation('FIPS:37')->get();
// or
$dataset = \Noaa::datasets()->withLocation(['FIPS:09', 'FIPS:10'])->get();

withStation(id)

id is a string containing a single valid station ID, or an array of strings representing multiple station IDs.

$dataset = \Noaa::datasets()->withStation('COOP:310090')->get();
// or
$dataset = \Noaa::datasets()->withStation(['COOP:310090', 'COOP:310184'])->get();

Data Categories

Returns the available data category(s) applicable to the given constraints (if any). The following optional constraint methods are available:

id is a string containing a single valid dataset ID, or an array of strings representing multiple dataset IDs.

$dataset = \Noaa::dataCategories()->withDataset('ACMH')->get();
// or
$dataset = \Noaa::dataCategories()->withDataset(['ACMH', 'GSOM'])->get();

withLocation(id)

id is a string containing a single valid location ID, or an array of strings representing multiple location IDs.

$dataset = \Noaa::dataCategories()->withLocation('FIPS:37')->get();
// or
$dataset = \Noaa::dataCategories()->withLocation(['FIPS:09', 'FIPS:10'])->get();

withStation(id)

id is a string containing a single valid station ID, or an array of strings representing multiple station IDs.

$dataset = \Noaa::dataCategories()->withStation('COOP:310090')->get();
// or
$dataset = \Noaa::dataCategories()->withStation(['COOP:310090', 'COOP:310184'])->get();

Data Types

Returns the available data type(s) applicable to the given constraints (if any). The following optional constraint methods are available:
