A DATA SET is a series of observations collected by the same methodology. Each data set should have documentation sufficient for someone unfamiliar with the research to replicate the study. Data sets may be broken into subsets (data files) that are discrete in space and time, in that order. The documentation for a data set should include all spatial and temporal subdivisions of the data.

DATA SET IDENTIFIER: USDC NOAA's National Climatic Data Center (NCDC) monthly average minimum temperature

PROJECT TITLE: Meteorology - Puerto Rico (USDC - LTER)

PROJECT DESCRIPTION: During LUQ LTER 1 (from 1988 to 1994) several meteorological data sets where obtained from other agencies for comparison. In 1993, historical daily precipitation and temperature data were obtained from the United States Department of Commerce NOAA NCDC from 5 stations, four of which are located at the East and South of the El Yunque Mountain (Fajardo, Río Blanco Lower and Upper, Pico del Este), and another at the North West (Río Grande). Historical streamfall data from the USGS were also obtained, but not summarized. These data can be obtained from the Puerto Rico USGS Web site at http://waterdata.usgs.gov/nwis.

Monthly sums of precipitation (P, in cm) and monthly averages (T, in oF) of the maximum and minimum air temperatures from NOAA NCDC were calculated and became part of the LUQ LTER data sets. Data are summarized through July 1992. Non-LUQ LTER users should obtain the daily data from this agency http://www.ncdc.noaa.gov).

We define a data file as a component of a data set. A data set can have only one data file or more. Basically, different data files have different data structures or format.

ABSTRACT:
Daily precipitation, maximum, and minimum air temperature at five stations in or near the LEF have been compiled by the National Climate Data Center. Here I present monthly sums of precipitation (P, in cm) and monthly averages (T, in oF) of the maximum and minimum air temperatures. Data are summarized through July 1992 and additional data will be added when it becomes available.  Station details are as follows:
