+ # Dataset Card for NASA Power Daily Weather Dataset
6
+
7
+ <!-- Provide a quick summary of the dataset. -->
8
+
9
+ This dataset contains daily solar and meteorological data downloaded from the [NASA Power API](https://power.larc.nasa.gov/)
10
+
11
+ ## Dataset Details
12
+
13
+ The dataset includes solar and meteorological variables collected from January 1st, 1984, to December 31st, 2022.
14
+ We downloaded 28 variables directly and estimated an additional 3 from the collected data. The data spans a 5 x 8 grid covering
15
+ the United States, Central America, and South America. Each grid rectangle contains 160 data points spaced 0.5 degrees apart in
16
+ latitude and longitude.

+ ## Dataset Structure
61
+
62
+ <!-- This section provides a description of the dataset fields, and additional information about the dataset structure such as criteria used to create the splits, relationships between data points, etc. -->
63
+
64
+ **raw:** unprocessed data dump from NASA pPower API in the JSON format.
65
+
66
+ **csvs:** Processed data in the csv format.
67
+
68
+ **pytorch:** Pytorch TensorDataset objects ready to be used in training. Each sample is a tuple of the following data:
69
+ * weather measurements (shape 365 x 31)
70
+ * coordinates (shape 1 x 2)
71
+ * index (1 x 2). the first number is the index of the current row since Jan 1, 1984. The second number is the temporal granularity, which is
72
+ * 1 for daily data, 7 for weekly data and 30 for monthly data.
73
+
74
+ ## Dataset Creation
75
+
76
+ ### Source Data
77
+
78
+ <!-- This section describes the source data (e.g. news text and headlines, social media posts, translated sentences, ...). -->
79
+ NASA Power API daily weather measurments
80
+
81
+ #### Data Processing
82
+
83
+ <!-- This section describes the data collection and processing process such as data selection criteria, filtering and normalization methods, tools and libraries used, etc. -->
84
+
85
+ - Missing values were backfilled.
86
+ - Leap year extra day was omitted. So, each year of the daily dataset has 365 days. Similarly, each year of weekly dataset has 52 weeks, and the monthly dataset has 12 columns.
87
+ - Data was pivoted. So each measurement has x columns where x is either 365, 52, or 12.
88
+ - `pytorch` data was standardized using the mean and std of the weather over the continental united states.
