  The WiDS Datathon 2023 focuses on a prediction task involving forecasting sub-seasonal temperatures (temperatures over a two-week period, in our case) within the United States. We are using a pre-prepared dataset consisting of weather and climate information for a number of US locations, for a number of start dates for the two-week observation, as well as the forecasted temperature and precipitation from a number of weather forecast models (we will reveal the source of our dataset after the competition closes). Each row in the data corresponds to a single location and a single start date for the two-week period. Your task is to predict the arithmetic mean of the maximum and minimum temperature over the next 14 days, for each location and start date.

  External Data Usage
16
  The datathon task can be tackled successfully without the use of external data. In fact, the degree to which we have anonymized the data would make joining additional data to the competition data difficult. However, participants who wish to do so may use additional external data for the purpose of building predictive models.

- Data Dictionary
19
  The WiDS 2023 Datathon is using a subset of a pre-prepared dataset in which the variables were gathered from the following datasets (source of the WiDS Datathon dataset will be revealed after the competition closes):
20
 
21
- Temperature: Daily maximum and minimum temperature measurements at 2 meters from 1979 onwards were obtained from NOAA’s Climate Prediction Center (CPC) Global Gridded Temperature dataset and converted to Celsius. The official contest target temperature variable is tmp2m = tmax+tmin / 2.
22
 
23
  ftp://ftp.cpc.ncep.noaa.gov/precip/PEOPLE/wd52ws/global_temp/
24
 
25
- Global precipitation: Daily precipitation data from 1979 onward were obtained from NOAA’s CPC Gauge-Based Analysis of Global Daily Precipitation [42] and converted to mm.
26
 
27
  ftp://ftp.cpc.ncep.noaa.gov/precip/CPC_UNI_PRCP/GAUGE_GLB/RT/
28
 
29
- U.S. precipitation: Daily U.S. precipitation data in mm were collected from the CPC Unified Gauge-Based Analysis of Daily Precipitation over CONUS. Measurements were replaced with sums over the ensuing two-week period.
30
 
31
  https://www.esrl.noaa.gov/psd/thredds/catalog/Datasets/cpc_us_precip/catalog.html
32
 
33
- Sea surface temperature and sea ice concentration: NOAA’s Optimum Interpolation Sea Surface Temperature (SST) dataset provides SST and sea ice concentration data, daily from 1981 to the present.
34
 
35
  ftp://ftp.cdc.noaa.gov/Projects/Datasets/noaa.oisst.v2.highres/
36
 
37
- Multivariate ENSO index (MEI): Bimonthly MEI values (MEI) from 1949 to the present, were obtained from NOAA/Earth System Research Laboratory. The MEI is a scalar summary of six variables (sea-level pressure, zonal and meridional surface wind components, SST, surface air temperature, and sky cloudiness) associated with El Niño/Southern Oscillation (ENSO), an ocean-atmosphere coupled climate mode.
38
 
39
  https://www.esrl.noaa.gov/psd/enso/mei/
40
 
41
- Madden-Julian oscillation (MJO): Daily MJO values since 1974 are provided by the Australian Government Bureau of Meteorology. MJO is a metric of tropical convection on daily to weekly timescales and can have a significant impact on the United States sub-seasonal climate. Measurements of phase and amplitude on the target date were extracted over the two-week period.
42
 
43
  http://www.bom.gov.au/climate/mjo/graphics/rmm.74toRealtime.txt
44
 
45
- Relative humidity, sea level pressure, and precipitable water for the entire atmosphere: NOAA’s National Center for Environmental Prediction (NCEP)/National Center for Atmospheric Research Reanalysis dataset contains daily relative humidity (rhum) near the surface (sigma level 0.995) from 1948 to the present and daily pressure at the surface (pres) from 1979 to the present.

47
  ftp://ftp.cdc.noaa.gov/Datasets/ncep.reanalysis/surface/

  ftp://ftp.cdc.noaa.gov/Datasets/ncep.reanalysis.dailyavgs/pressure/
52

- North American Multi-Model Ensemble (NMME): The North American Multi-Model Ensemble (NMME) is a collection of physics-based forecast models from various modeling centers in North America. Forecasts issued monthly from the Cansips, CanCM3, CanCM4, CCSM3, CCSM4, GFDL-CM2.1-aer04, GFDL-CM2.5, FLOR-A06 and FLOR-B01, NASA-GMAO-062012, and NCEP-CFSv2 models were downloaded from the IRI/LDEO Climate Data Library. Each forecast contains monthly mean predictions from 0.5 to 8.5 months ahead.

The prefix indicates from which of the above-listed file the variable was derived (e.g. Madden-Julian oscillation, pressure, and potential evaporation from NOAA's surface_gauss etc), the suffix indicates the specific type of information that was extracted from the file.
