water: change log. From 09/09/2015. Most recent changes first / on top. Guillermo OLMEDO

VERSION 0.5

• Added maxit parameter to calcH to control the maximun number of iterations.
• Added an optional constrain to the selection of anchors pixels using the location of the weather station and a 30km buffer.
• Changed default value for Z.om.ws in calcH. (From 0.0018 to 0.03)
• Added a new parameter to calcAnchors, available for both methods: buffer. buffer allow to set the minimun distance between two anchor pixels of the same kind
• Added a new method for calcAnchors = "CITRA-MCBbc". This method chooses the coldest and hottest anchors pixels availables. Previous method ("CITRA-MCBr") chooses random pixel who meets the conditions. CITRA-MCBbc is now the default method for calcAnchors
• General remote sensing functions moved to a separate file
• loadImage detects when there is more than 1 image on the working folder
• Rn, G, H, LE are restricted to values > 0
• Improvements to anchors pixels selection: more releaxed hot temperature criterium, distance, mean of many pixels, etc
• Added two methods for land surface estimation: single channel and split windows. Split windows only works for Landsat 8.
• loadImage now loads thermal data also: low gain for L7 and both bands for L8
• Fixed big bug when estimating ETo with a large weather station file

VERSION 0.3.2

• Solved errors when using non ASCII characters
• Fixes some bug who prevent using water with L8 data
• More flexibility on band names and changes to reflect the changes on USGS's ESPA file naming
• Improvement to plot.waterWeatherStation to plot only data from the sattelite overpass when the object was created using a MTL file.

VERSION 0.3

• First release to CRAN!

VERSION 0.2.9

• Added dailyET function to calc and sum hourly ET for a complete day
• Added new parameter to hourlyET and dailyET to choose between ETo or ETr
• read.WSdata doesn't require a Landsat metadata anymore. Now you can process weatherstation data without a landsat flyby. print method changed to reflect this
• function METRIC.EB now accepts many parameters for method of the included functions. For example, you can set with method you choose for LAI estimation
• We're approaching CRAN launch date. Changed version numbering to reflect this. First CRAN version will be 0.3

VERSION 0.0.2.4

• Added function to prepare data from Weather Station and calc weather conditions at satellite flyby.
• Added function to calculate Surface Energy Balance using METRIC

VERSION 0.0.2.3

• Rename sensibleHeatFlux() to sensibleHeatFlux_old()
• Remove sensibleHeatFlux.CITRA()
• Split sensibleHeatFlux in 2 new functions:
  • calcAnchors() for anchors points
  • calcH() for the iterative process to calculate H and dT
• Added function to estimate Net Radiation
